| Summary: Transport Layer Security protocol suite | |
mbedtls implements the SSL 3.0, TLS 1.0, 1.1 and 1.2 protocols. It supports a number of extensions such as SSL Session Tickets (RFC 5077), Server Name Indication (SNI) (RFC 6066), Truncated HMAC (RFC 6066), Max Fragment Length (RFC 6066), Secure Renegotiation (RFC 5746) and Application Layer Protocol Negotiation (ALPN). It understands the RSA, (EC)DH(E)-RSA, (EC)DH(E)-PSK and RSA-PSK key exchanges.

* Wed Dec 21 2022 Alexander Bergmann <abergmann@suse.com>
- Update to 2.28.2: (bsc#1206576, CVE-2022-46393)
Security:
* Fix potential heap buffer overread and overwrite in DTLS if
MBEDTLS_SSL_DTLS_CONNECTION_ID is enabled and
MBEDTLS_SSL_CID_IN_LEN_MAX > 2 * MBEDTLS_SSL_CID_OUT_LEN_MAX.
* An adversary with access to precise enough information about memory
accesses (typically, an untrusted operating system attacking a secure
enclave) could recover an RSA private key after observing the victim
performing a single private-key operation if the window size used for the
exponentiation was 3 or smaller. Found and reported by Zili KOU,
Wenjian HE, Sharad Sinha, and Wei ZHANG. See "Cache Side-channel Attacks
and Defenses of the Sliding Window Algorithm in TEEs" - Design, Automation
and Test in Europe 2023.
Bugfix:
* Fix a long-standing build failure when building x86 PIC code with old
gcc (4.x). The code will be slower, but will compile. We do however
recommend upgrading to a more recent compiler instead. Fixes #1910.
* Fix support for little-endian Microblaze when MBEDTLS_HAVE_ASM is defined.
Contributed by Kazuyuki Kimura to fix #2020.
* Use double quotes to include private header file psa_crypto_cipher.h.
Fixes 'file not found with include' error when building with Xcode.
* Fix handling of broken symlinks when loading certificates using
mbedtls_x509_crt_parse_path(). Instead of returning an error as soon as a
broken link is encountered, skip the broken link and continue parsing
other certificate files. Contributed by Eduardo Silva in #2602.
* Fix a compilation error when using CMake with an IAR toolchain.
Fixes #5964.
* Fix bugs and missing dependencies when building and testing
configurations with only one encryption type enabled in TLS 1.2.
* Provide the missing definition of mbedtls_setbuf() in some configurations
with MBEDTLS_PLATFORM_C disabled. Fixes #6118, #6196.
* Fix compilation errors when trying to build with
PSA drivers for AEAD (GCM, CCM, Chacha20-Poly1305).
* Fix memory leak in ssl_parse_certificate_request() caused by
mbedtls_x509_get_name() not freeing allocated objects in case of error.
Change mbedtls_x509_get_name() to clean up allocated objects on error.
* Fix checks on PK in check_config.h for builds with PSA and RSA. This does
not change which builds actually work, only moving a link-time error to
an early check.
* Fix ECDSA verification, where it was not always validating the
public key. This bug meant that it was possible to verify a
signature with an invalid public key, in some cases. Reported by
Guido Vranken using Cryptofuzz in #4420.
* Fix a possible null pointer dereference if a memory allocation fails
in TLS PRF code. Reported by Michael Madsen in #6516.
* Fix a bug in which mbedtls_x509_crt_info() would produce non-printable
bytes when parsing certificates containing a binary RFC 4108
HardwareModuleName as a Subject Alternative Name extension. Hardware
serial numbers are now rendered in hex format. Fixes #6262.
* Fix bug in error reporting in dh_genprime.c where upon failure,
the error code returned by mbedtls_mpi_write_file() is overwritten
and therefore not printed.
* In the bignum module, operations of the form (-A) - (+A) or (-A) - (-A)
with A > 0 created an unintended representation of the value 0 which was
not processed correctly by some bignum operations. Fix this. This had no
consequence on cryptography code, but might affect applications that call
bignum directly and use negative numbers.
* Fix undefined behavior (typically harmless in practice) of
mbedtls_mpi_add_mpi(), mbedtls_mpi_add_abs() and mbedtls_mpi_add_int()
when both operands are 0 and the left operand is represented with 0 limbs.
* Fix undefined behavior (typically harmless in practice) when some bignum
functions receive the most negative value of mbedtls_mpi_sint. Credit
to OSS-Fuzz. Fixes #6597.
* Fix undefined behavior (typically harmless in practice) in PSA ECB
encryption and decryption.
* Fri Nov 04 2022 Mia Herkt <mia@0x0.st>
- Update to 2.28.1: (CVE-2022-35409)
Default behavior changes
* mbedtls_cipher_set_iv will now fail with ChaCha20 and
ChaCha20+Poly1305 for IV lengths other than 12. The library was
silently overwriting this length with 12, but did not inform
the caller about it.
gh#Mbed-TLS/mbedtls#4301
Features
* When MBEDTLS_PSA_CRYPTO_CONFIG is enabled, you may list the PSA
crypto feature requirements in the file named by the new macro
MBEDTLS_PSA_CRYPTO_CONFIG_FILE instead of the default
psa/crypto_config.h. Furthermore you may name an additional
file to include after the main file with the macro
MBEDTLS_PSA_CRYPTO_USER_CONFIG_FILE.
Security
* Zeroize dynamically-allocated buffers used by the PSA Crypto
key storage module before freeing them. These buffers contain
secret key material, and could thus potentially leak the key
through freed heap.
* Fix a potential heap buffer overread in TLS 1.2 server-side
when MBEDTLS_USE_PSA_CRYPTO is enabled, an opaque key (created
with mbedtls_pk_setup_opaque()) is provisioned, and a static
ECDH ciphersuite is selected. This may result in an application
crash or potentially an information leak.
* Fix a buffer overread in DTLS ClientHello parsing in servers
with MBEDTLS_SSL_DTLS_CLIENT_PORT_REUSE enabled.
An unauthenticated client or a man-in-the-middle could cause a
DTLS server to read up to 255 bytes after the end of the SSL
input buffer. The buffer overread only happens when
MBEDTLS_SSL_IN_CONTENT_LEN is less than a threshold that
depends on the exact configuration: 258 bytes if using
mbedtls_ssl_cookie_check(), and possibly up to 571 bytes with
a custom cookie check function.
Reported by the Cybeats PSI Team.
Bugfix
* Fix a memory leak if mbedtls_ssl_config_defaults() is called
twice.
* Fix several bugs (warnings, compiler and linker errors, test
failures) in reduced configurations when MBEDTLS_USE_PSA_CRYPTO
is enabled.
* Fix a bug in (D)TLS curve negotiation: when
MBEDTLS_USE_PSA_CRYPTO was enabled and an ECDHE-ECDSA or
ECDHE-RSA key exchange was used, the client would fail to check
that the curve selected by the server for ECDHE was indeed one
that was offered. As a result, the client would accept any
curve that it supported, even if that curve was not allowed
according to its configuration.
gh#Mbed-TLS/mbedtls#5291
* Fix unit tests that used 0 as the file UID. This failed on some
implementations of PSA ITS.
gh#Mbed-TLS/mbedtls#3838
* Fix API violation in mbedtls_md_process() test by adding a call
to mbedtls_md_starts().
gh#Mbed-TLS/mbedtls#2227
* Fix compile errors when MBEDTLS_HAVE_TIME is not defined.
Add tests to catch bad uses of time.h.
* Fix bug in the alert sending function
mbedtls_ssl_send_alert_message() potentially leading to
corrupted alert messages being sent in case the function needs
to be re-called after initially returning
MBEDTLS_SSL_WANT_WRITE.
gh#Mbed-TLS/mbedtls#1916
* In configurations with MBEDTLS_SSL_DTLS_CONNECTION_ID enabled
but none of MBEDTLS_SSL_HW_RECORD_ACCEL,
MBEDTLS_SSL_EXPORT_KEYS or MBEDTLS_DEBUG_C, DTLS handshakes
using CID would crash due to a null pointer dereference.
Fix this.
gh#Mbed-TLS/mbedtls#3998
* Fix incorrect documentation of mbedtls_x509_crt_profile. The
previous documentation stated that the allowed_pks field
applies to signatures only, but in fact it does apply to the
public key type of the end entity certificate, too.
gh#Mbed-TLS/mbedtls#1992
* Fix PSA cipher multipart operations using ARC4. Previously, an
IV was required but discarded. Now, an IV is rejected, as it
should be.
* Fix undefined behavior in mbedtls_asn1_find_named_data(), where
val is not NULL and val_len is zero. psa_raw_key_agreement()
now returns PSA_ERROR_BUFFER_TOO_SMALL when applicable.
gh#Mbed-TLS/mbedtls#5735
* Fix a bug in the x25519 example program where the removal of
MBEDTLS_ECDH_LEGACY_CONTEXT caused the program not to run.
gh#Mbed-TLS/mbedtls#4901
gh#Mbed-TLS/mbedtls#3191
* Encode X.509 dates before 1/1/2000 as UTCTime rather than
GeneralizedTime.
gh#Mbed-TLS/mbedtls#5465
* Fix order value of curve x448.
* Fix string representation of DNs when outputting values
containing commas and other special characters, conforming to
RFC 1779.
gh#Mbed-TLS/mbedtls#769
* Silence a warning from GCC 12 in the selftest program.
gh#Mbed-TLS/mbedtls#5974
* Fix mbedtls_asn1_write_mpi() writing an incorrect encoding of
0.
* Fix resource leaks in mbedtls_pk_parse_public_key() in low
memory conditions.
* Fix server connection identifier setting for outgoing encrypted
records on DTLS 1.2 session resumption. After DTLS 1.2 session
resumption with connection identifier, the Mbed TLS client now
properly sends the server connection identifier in encrypted
record headers.
gh#Mbed-TLS/mbedtls#5872
* Fix a null pointer dereference when performing some operations
on zero represented with 0 limbs (specifically
mbedtls_mpi_mod_int() dividing by 2, and
mbedtls_mpi_write_string() in base 2).
* Fix record sizes larger than 16384 being sometimes accepted
despite being non-compliant. This could not lead to a buffer
overflow. In particular, application data size was already
checked correctly.
* Mon Jan 17 2022 Guillaume GARDET <guillaume.gardet@opensuse.org>
- Fix baselib.conf
* Thu Jan 13 2022 Guillaume GARDET <guillaume.gardet@opensuse.org>
- Update to 2.28.0: (bsc#1193979, CVE-2021-45450)
API changes
* Some fields of mbedtls_ssl_session and mbedtls_ssl_config are in a
different order. This only affects applications that define such
structures directly or serialize them.
Requirement changes
* Sign-magnitude and one's complement representations for signed integers are
not supported. Two's complement is the only supported representation.
Removals
* Remove config option MBEDTLS_TLS_DEFAULT_ALLOW_SHA1_IN_CERTIFICATES,
which allowed SHA-1 in the default TLS configuration for certificate
signing. It was intended to facilitate the transition in environments
with SHA-1 certificates. SHA-1 is considered a weak message digest and
its use constitutes a security risk.
* Remove the partial support for running unit tests via Greentea on Mbed OS,
which had been unmaintained since 2018.
Features
* The identifier of the CID TLS extension can be configured by defining
MBEDTLS_TLS_EXT_CID at compile time.
* Warn if errors from certain functions are ignored. This is currently
supported on GCC-like compilers and on MSVC and can be configured through
the macro MBEDTLS_CHECK_RETURN. The warnings are always enabled
(where supported) for critical functions where ignoring the return
value is almost always a bug. Enable the new configuration option
MBEDTLS_CHECK_RETURN_WARNING to get warnings for other functions. This
is currently implemented in the AES, DES and md modules, and will be
extended to other modules in the future.
* Add missing PSA macros declared by PSA Crypto API 1.0.0:
PSA_ALG_IS_SIGN_HASH, PSA_ALG_NONE, PSA_HASH_BLOCK_LENGTH, PSA_KEY_ID_NULL.
* Add new API mbedtls_ct_memcmp for constant time buffer comparison.
* Add PSA API definition for ARIA.
Security
* Zeroize several intermediate variables used to calculate the expected
value when verifying a MAC or AEAD tag. This hardens the library in
case the value leaks through a memory disclosure vulnerability. For
example, a memory disclosure vulnerability could have allowed a
man-in-the-middle to inject fake ciphertext into a DTLS connection.
* In psa_cipher_generate_iv() and psa_cipher_encrypt(), do not read back
from the output buffer. This fixes a potential policy bypass or decryption
oracle vulnerability if the output buffer is in memory that is shared with
an untrusted application.
* Fix a double-free that happened after mbedtls_ssl_set_session() or
mbedtls_ssl_get_session() failed with MBEDTLS_ERR_SSL_ALLOC_FAILED
(out of memory). After that, calling mbedtls_ssl_session_free()
and mbedtls_ssl_free() would cause an internal session buffer to
be free()'d twice.
Bugfix
* Stop using reserved identifiers as local variables. Fixes #4630.
* The GNU makefiles invoke python3 in preference to python except on Windows.
* The check was accidentally not performed when cross-compiling for Windows
on Linux. Fix this. Fixes #4774.
* Prevent divide by zero if either of PSA_CIPHER_ENCRYPT_OUTPUT_SIZE() or
PSA_CIPHER_UPDATE_OUTPUT_SIZE() were called using an asymmetric key type.
* Fix a parameter set but unused in psa_crypto_cipher.c. Fixes #4935.
* Don't use the obsolete header path sys/fcntl.h in unit tests.
These header files cause compilation errors in musl.
Fixes #4969.
* Fix missing constraints on x86_64 and aarch64 assembly code
for bignum multiplication that broke some bignum operations with
(at least) Clang 12.
Fixes #4116, #4786, #4917, #4962.
* Fix mbedtls_cipher_crypt: AES-ECB when MBEDTLS_USE_PSA_CRYPTO is enabled.
* Failures of alternative implementations of AES or DES single-block
functions enabled with MBEDTLS_AES_ENCRYPT_ALT, MBEDTLS_AES_DECRYPT_ALT,
MBEDTLS_DES_CRYPT_ECB_ALT or MBEDTLS_DES3_CRYPT_ECB_ALT were ignored.
This does not concern the implementation provided with Mbed TLS,
where this function cannot fail, or full-module replacements with
MBEDTLS_AES_ALT or MBEDTLS_DES_ALT. Reported by Armelle Duboc in #1092.
* Some failures of HMAC operations were ignored. These failures could only
happen with an alternative implementation of the underlying hash module.
* Fix the error returned by psa_generate_key() for a public key. Fixes #4551.
* Fix the build of sample programs when neither MBEDTLS_ERROR_C nor
MBEDTLS_ERROR_STRERROR_DUMMY is enabled.
* Fix PSA_ALG_RSA_PSS verification accepting an arbitrary salt length.
This algorithm now accepts only the same salt length for verification
that it produces when signing, as documented. Use the new algorithm
PSA_ALG_RSA_PSS_ANY_SALT to accept any salt length. Fixes #4946.
* The existing predicate macro name PSA_ALG_IS_HASH_AND_SIGN is now reserved
for algorithm values that fully encode the hashing step, as per the PSA
Crypto API specification. This excludes PSA_ALG_RSA_PKCS1V15_SIGN_RAW and
PSA_ALG_ECDSA_ANY. The new predicate macro PSA_ALG_IS_SIGN_HASH covers
all algorithms that can be used with psa_{sign,verify}_hash(), including
these two.
* Fix issue in Makefile on Linux with SHARED=1, that caused shared libraries
not to list other shared libraries they need.
* Fix a bug in mbedtls_gcm_starts() when the bit length of the iv
exceeds 2^32. Fixes #4884.
* Fix an uninitialized variable warning in test_suite_ssl.function with GCC
version 11.
* Fix the build when no SHA2 module is included. Fixes #4930.
* Fix the build when only the bignum module is included. Fixes #4929.
* Fix a potential invalid pointer dereference and infinite loop bugs in
pkcs12 functions when the password is empty. Fix the documentation to
better describe the inputs to these functions and their possible values.
Fixes #5136.
* The key usage flags PSA_KEY_USAGE_SIGN_MESSAGE now allows the MAC
operations psa_mac_compute() and psa_mac_sign_setup().
* The key usage flags PSA_KEY_USAGE_VERIFY_MESSAGE now allows the MAC
operations psa_mac_verify() and psa_mac_verify_setup().
Changes
* Set config option MBEDTLS_TLS_DEFAULT_ALLOW_SHA1_IN_KEY_EXCHANGE to be
disabled by default.
* Improve the performance of base64 constant-flow code. The result is still
slower than the original non-constant-flow implementation, but much faster
than the previous constant-flow implementation. Fixes #4814.
* Indicate in the error returned if the nonce length used with
ChaCha20-Poly1305 is invalid, and not just unsupported.
* The mbedcrypto library includes a new source code module constant_time.c,
containing various functions meant to resist timing side channel attacks.
* This module does not have a separate configuration option, and functions
from this module will be included in the build as required. Currently
most of the interface of this module is private and may change at any
time.
* Tue Jul 20 2021 Pedro Monreal <pmonreal@suse.com>
- Update to 2.27.0:
API changes:
* Update AEAD output size macros to bring them in line with the PSA Crypto
API version 1.0 spec. This version of the spec parameterizes them on the
key type used, as well as the key bit-size in the case of
PSA_AEAD_TAG_LENGTH.
The old versions of these macros were renamed and deprecated as follows:
- PSA_AEAD_TAG_LENGTH -> PSA_AEAD_TAG_LENGTH_1_ARG
- PSA_AEAD_ENCRYPT_OUTPUT_SIZE -> PSA_AEAD_ENCRYPT_OUTPUT_SIZE_2_ARG
- PSA_AEAD_DECRYPT_OUTPUT_SIZE -> PSA_AEAD_DECRYPT_OUTPUT_SIZE_2_ARG
- PSA_AEAD_UPDATE_OUTPUT_SIZE -> PSA_AEAD_UPDATE_OUTPUT_SIZE_2_ARG
- PSA_AEAD_FINISH_OUTPUT_SIZE -> PSA_AEAD_FINISH_OUTPUT_SIZE_1_ARG
- PSA_AEAD_VERIFY_OUTPUT_SIZE -> PSA_AEAD_VERIFY_OUTPUT_SIZE_1_ARG
* Implement one-shot cipher functions, psa_cipher_encrypt and
psa_cipher_decrypt, according to the PSA Crypto API 1.0.0
specification.
Features:
* Add mbedtls_rsa_rsassa_pss_sign_ext() function allowing to generate a
signature with a specific salt length. This function allows to validate
test cases provided in the NIST's CAVP test suite.
* Added support for built-in driver keys through the PSA opaque crypto
driver interface. Refer to the documentation of
MBEDTLS_PSA_CRYPTO_BUILTIN_KEYS for more information.
* Implement psa_sign_message() and psa_verify_message().
* The new function mbedtls_mpi_random() generates a random value in a
given range uniformly.
* Implement psa_mac_compute() and psa_mac_verify() as defined in the
PSA Cryptograpy API 1.0.0 specification.
* MBEDTLS_ECP_MAX_BITS is now determined automatically from the configured
curves and no longer needs to be configured explicitly to save RAM.
Security
* Fix a bias in the generation of finite-field Diffie-Hellman-Merkle (DHM)
private keys and of blinding values for DHM and elliptic curves (ECP)
computations.
* Fix a potential side channel vulnerability in ECDSA ephemeral key generation.
An adversary who is capable of very precise timing measurements could
learn partial information about the leading bits of the nonce used for the
signature, allowing the recovery of the private key after observing a
large number of signature operations. This completes a partial fix in
Mbed TLS 2.20.0.
* It was possible to configure MBEDTLS_ECP_MAX_BITS to a value that is
too small, leading to buffer overflows in ECC operations. Fail the build
in such a case.
* An adversary with access to precise enough information about memory
accesses (typically, an untrusted operating system attacking a secure
enclave) could recover an RSA private key after observing the victim
performing a single private-key operation.
* An adversary with access to precise enough timing information (typically, a
co-located process) could recover a Curve25519 or Curve448 static ECDH key
after inputting a chosen public key and observing the victim performing the
corresponding private-key operation.
Bugfix
* Add printf function attributes to mbedtls_debug_print_msg to ensure we
get printf format specifier warnings.
* Fix premature fopen() call in mbedtls_entropy_write_seed_file which may
lead to seed file corruption in the case where the path to the seed file is
equal to MBEDTLS_PLATFORM_STD_NV_SEED_FILE.
* PSA functions other than psa_open_key now return PSA_ERROR_INVALID_HANDLE
rather than PSA_ERROR_DOES_NOT_EXIST for an invalid handle, bringing them
in line with version 1.0.0 of the specification.
* PSA functions creating a key now return PSA_ERROR_INVALID_ARGUMENT rather
than PSA_ERROR_INVALID_HANDLE when the identifier specified for the key
to create is not valid, bringing them in line with version 1.0.0 of the
specification.
* Fix some cases in the bignum module where the library constructed an
unintended representation of the value 0 which was not processed
correctly by some bignum operations. This could happen when
mbedtls_mpi_read_string() was called on "-0", or when
mbedtls_mpi_mul_mpi() and mbedtls_mpi_mul_int() was called with one of
the arguments being negative and the other being 0.
* Fix a bug in ECDSA that would cause it to fail when the hash is all-bits
zero.
* Fix a compilation error when MBEDTLS_ECP_RANDOMIZE_MXZ_ALT is
defined.
* Fix an incorrect error code when parsing a PKCS#8 private key.
* In a TLS client, enforce the Diffie-Hellman minimum parameter size
set with mbedtls_ssl_conf_dhm_min_bitlen() precisely. Before, the
minimum size was rounded down to the nearest multiple of 8.
* In library/net_sockets.c, _POSIX_C_SOURCE and _XOPEN_SOURCE are
defined to specific values. If the code is used in a context
where these are already defined, this can result in a compilation
error. Instead, assume that if they are defined, the values will
be adequate to build Mbed TLS.
* The cipher suite TLS-RSA-WITH-CAMELLIA-256-GCM-SHA384 was not available
when SHA-1 was disabled and was offered when SHA-1 was enabled but SHA-384
was disabled. Fix the dependency.
* Do not offer SHA384 cipher suites when SHA-384 is disabled.
* With MBEDTLS_PSA_CRYPTO_C disabled, some functions were getting built
nonetheless, resulting in undefined reference errors when building a
shared library.
* Fix test suite code on platforms where int32_t is not int, such as
Arm Cortex-M.
* Fix some issues affecting MBEDTLS_ARIA_ALT implementations: a misplaced
directive in a header and a missing initialization in the self-test.
* Fix a missing initialization in the Camellia self-test, affecting
MBEDTLS_CAMELLIA_ALT implementations.
* Restore the ability to configure PSA via Mbed TLS options to support RSA
key pair operations but exclude RSA key generation. When MBEDTLS_GENPRIME
is not defined PSA will no longer attempt to use mbedtls_rsa_gen_key().
* Fix a regression introduced in 2.24.0 which broke (D)TLS CBC ciphersuites
(when the encrypt-then-MAC extension is not in use) with some ALT
implementations of the underlying hash (SHA-1, SHA-256, SHA-384), causing
the affected side to wrongly reject valid messages.
* Remove outdated check-config.h check that prevented implementing the
timing module on Mbed OS.
* Fix PSA_ALG_TLS12_PRF and PSA_ALG_TLS12_PSK_TO_MS being too permissive
about missing inputs.
* Fix a resource leak in a test suite with an alternative AES
implementation.
* Fix a crash in mbedtls_mpi_debug_mpi on a bignum having 0 limbs. This
could notably be triggered by setting the TLS debug level to 3 or above
and using a Montgomery curve for the key exchange.
* psa_verify_hash() was relying on implementation-specific behavior of
mbedtls_rsa_rsassa_pss_verify() and was causing failures in some _ALT
implementations. This reliance is now removed.
* Disallow inputs of length different from the corresponding hash when
signing or verifying with PSA_ALG_RSA_PSS (The PSA Crypto API mandates
that PSA_ALG_RSA_PSS uses the same hash throughout the algorithm.)
* Fix a null pointer dereference when mbedtls_mpi_exp_mod() was called with
A=0 represented with 0 limbs. Up to and including Mbed TLS 2.26, this bug
could not be triggered by code that constructed A with one of the
mbedtls_mpi_read_xxx functions (including in particular TLS code) since
those always built an mpi object with at least one limb.
* Fix mbedtls_mpi_gcd(G,A,B) when the value of B is zero. This had no
effect on Mbed TLS's internal use of mbedtls_mpi_gcd(), but may affect
applications that call mbedtls_mpi_gcd() directly.
* The PSA API no longer allows the creation or destruction of keys with a
read-only lifetime. The persistence level PSA_KEY_PERSISTENCE_READ_ONLY
can now only be used as intended, for keys that cannot be modified through
normal use of the API.
* When MBEDTLS_PSA_CRYPTO_SPM is enabled, crypto_spe.h was not included
in all the right places. Include it from crypto_platform.h, which is
the natural place.
* mbedtls_pk_sign() and mbedtls_pk_verify() and their extended and
restartable variants now always honor the specified hash length if
nonzero. Before, for RSA, hash_len was ignored in favor of the length of
the specified hash algorithm.
* Fix which alert is sent in some cases to conform to the
applicable RFC: on an invalid Finished message value, an
invalid max_fragment_length extension, or an
unsupported extension used by the server.
* Correct (change from 12 to 13 bytes) the value of the macro describing the
maximum nonce length returned by psa_aead_generate_nonce().
Changes
* Add extra printf compiler warning flags to builds.
* Fix memsan build false positive in x509_crt.c with Clang 11
* Fix the setting of the read timeout in the DTLS sample programs.
* Remove the AES sample application programs/aes/aescrypt2 which shows
bad cryptographic practice.
* Alternative implementations of CMAC may now opt to not support 3DES as a
CMAC block cipher, and still pass the CMAC self test.
* Remove configs/config-psa-crypto.h, which was identical to the default
configuration except for having some extra cryptographic mechanisms
enabled and for unintended differences. This configuration was primarily
intended to demonstrate the PSA API, and lost most of its usefulness when
MBEDTLS_PSA_CRYPTO_C became enabled by default.
* When building the test suites with GNU make, invoke python3 or python, not
python2, which is no longer supported upstream.
* When using session cache based session resumption on the server,
double-check that custom session cache implementations return
sessions which are consistent with the negotiated ciphersuite
and compression method.
* Fix build failure on MinGW toolchain when __USE_MING_ANSI_STDIO is on.
When that flag is on, standard GNU C printf format specifiers
should be used.
* Reduce the default value of MBEDTLS_ECP_WINDOW_SIZE. This reduces RAM usage
during ECC operations at a negligible performance cost.
* mbedtls_mpi_read_binary(), mbedtls_mpi_read_binary_le() and
mbedtls_mpi_read_string() now construct an mbedtls_mpi object with 0 limbs
when their input has length 0. Note that this is an implementation detail
and can change at any time, so this change should be transparent, but it
may result in mbedtls_mpi_write_binary() or mbedtls_mpi_write_string()
now writing an empty string where it previously wrote one or more
zero digits when operating from values constructed with an mpi_read
function and some mpi operations.
* Implicitly add PSA_KEY_USAGE_SIGN_MESSAGE key usage policy flag when
PSA_KEY_USAGE_SIGN_HASH flag is set and PSA_KEY_USAGE_VERIFY_MESSAGE flag
when PSA_KEY_USAGE_VERIFY_HASH flag is set. This usage flag extension
is also applied when loading a key from storage.
* Remove mbedtls-4237.patch upstream

- update to 2.25.0:
* This release of Mbed TLS provides bug fixes, minor enhancements and new
features. This release includes fixes for security issues.
* see https://github.com/ARMmbed/mbedtls/releases/tag/v2.25.0
* The functions mbedtls_cipher_auth_encrypt() and
mbedtls_cipher_auth_decrypt() would write past the minimum documented size
of the output buffer when used with NIST_KW. As a result, code using those
functions as documented with NIST_KW could have a buffer overwrite of up to
15 bytes, with consequences ranging up to arbitrary code execution
depending on the location of the output buffer.
* Limit the size of calculations performed by mbedtls_mpi_exp_mod to
MBEDTLS_MPI_MAX_SIZE to prevent a potential denial of service when generating
Diffie-Hellman key pairs. Credit to OSS-Fuzz.
* A failure of the random generator was ignored in mbedtls_mpi_fill_random(),
which is how most uses of randomization in asymmetric cryptography (including
key generation, intermediate value randomization and blinding) are implemented.
This could cause failures or the silent use of non-random values. A random
generator can fail if it needs reseeding and cannot not obtain entropy, or due
to an internal failure (which, for Mbed TLS's own CTR_DRBG or HMAC_DRBG, can
only happen due to a misconfiguration).
* Fix a compliance issue whereby we were not checking the tag on the algorithm
parameters (only the size) when comparing the signature in the description part
of the cert to the real signature. This meant that a NULL algorithm parameters
entry would look identical to an array of REAL (size zero) to the library and
thus the certificate would be considered valid. However, if the parameters do
not match in any way then the certificate should be considered invalid, and
indeed OpenSSL marks these certs as invalid when mbedtls did not. Many thanks
to guidovranken who found this issue via differential fuzzing and reported it
in #3629.
* Zeroising of local buffers and variables which are used for calculations in
mbedtls_pkcs5_pbkdf2_hmac(), mbedtls_internal_sha*_process(),
mbedtls_internal_md*_process() and mbedtls_internal_ripemd160_process()
functions to erase sensitive data from memory. Reported by Johan Malmgren and
Johan Uppman Bruce from Sectra.

- update to 2.24.0:
* see https://github.com/ARMmbed/mbedtls/releases/tag/v2.24.0
* Fix a vulnerability in the verification of X.509 certificates when matching
the expected common name (the cn argument of mbedtls_x509_crt_verify())
with the actual certificate name: when the subjecAltName extension is
present, the expected name was compared to any name in that extension
regardless of its type. This means that an attacker could for example
impersonate a 4-bytes or 16-byte domain by getting a certificate for the
corresponding IPv4 or IPv6 (this would require the attacker to control that
IP address, though). Similar attacks using other subjectAltName name types
might be possible.
* When checking X.509 CRLs, a certificate was only considered as revoked if
its revocationDate was in the past according to the local clock if
available. In particular, on builds without MBEDTLS_HAVE_TIME_DATE,
certificates were never considered as revoked. On builds with
MBEDTLS_HAVE_TIME_DATE, an attacker able to control the local clock (for
example, an untrusted OS attacking a secure enclave) could prevent
revocation of certificates via CRLs. Fixed by no longer checking the
revocationDate field, in accordance with RFC 5280. Reported by yuemonangong
in #3340. Reported independently and fixed by Raoul Strackx and Jethro
* In (D)TLS record decryption, when using a CBC ciphersuites without the
Encrypt-then-Mac extension, use constant code flow memory access patterns
to extract and check the MAC. This is an improvement to the existing
countermeasure against Lucky 13 attacks. The previous countermeasure was
effective against network-based attackers, but less so against local
attackers. The new countermeasure defends against local attackers, even if
they have access to fine-grained measurements. In particular, this fixes a
local Lucky 13 cache attack found and reported by Tuba Yavuz, Farhaan
Fowze, Ken (Yihan) Bai, Grant Hernandez, and Kevin Butler (University of
Florida) and Dave Tian (Purdue University).
* Fix side channel in RSA private key operations and static (finite-field)
Diffie-Hellman. An adversary with precise enough timing and memory access
information (typically an untrusted operating system attacking a secure
enclave) could bypass an existing counter-measure (base blinding) and
potentially fully recover the private key.
* Fix a 1-byte buffer overread in mbedtls_x509_crl_parse_der(). Credit to
OSS-Fuzz for detecting the problem and to Philippe Antoine for pinpointing
the problematic code.
* Zeroising of plaintext buffers in mbedtls_ssl_read() to erase unused
application data from memory.
* Mon Sep 07 2020 Stefan Brüns <stefan.bruens@rwth-aachen.de>

- update to 2.23.0:
a lot of changes see https://github.com/ARMmbed/mbedtls/releases/tag/v2.23.0
* Fix a side channel vulnerability in modular exponentiation that could reveal an RSA private key used in a secure enclave. Noticed by Sangho Lee, Ming-Wei Shih, Prasun Gera, Taesoo Kim and Hyesoon Kim (Georgia Institute of Technology); and Marcus Peinado (Microsoft Research). Reported by Raoul Strackx (Fortanix) in #3394.
* Fix side channel in mbedtls_ecp_check_pub_priv() and mbedtls_pk_parse_key() / mbedtls_pk_parse_keyfile() (when loading a private key that didn't include the uncompressed public key), as well as mbedtls_ecp_mul() / mbedtls_ecp_mul_restartable() when called with a NULL f_rng argument. An attacker with access to precise enough timing and memory access information (typically an untrusted operating system attacking a secure enclave) could fully recover the ECC private key. Found and reported by Alejandro Cabrera Aldaya and Billy Brumley.
* Fix issue in Lucky 13 counter-measure that could make it ineffective when hardware accelerators were used (using one of the MBEDTLS_SHAxxx_ALT macros). This would cause the original Lucky 13 attack to be possible in those configurations, allowing an active network attacker to recover plaintext after repeated timing measurements under some conditions. Reported and fix suggested by Luc Perneel in #3246.

* Mon Jan 07 2019 Martin Pluskal <mpluskal@suse.com>
- Update to version 2.16.0:
Features
* Add a new config.h option of MBEDTLS_CHECK_PARAMS that enables validation of parameters in the API. This allows detection of obvious misuses of the API, such as passing NULL pointers. The API of existing functions hasn't changed, but requirements on parameters have been made more explicit in the documentation. See the corresponding API documentation for each function to see for which parameter values it is defined. This feature is disabled by default. See its API documentation in config.h for additional steps you have to take when enabling it.
API Changes
* The following functions in the random generator modules have been deprecated and replaced as shown below. The new functions change the return type from void to int to allow returning error codes when using MBEDTLS_<MODULE>_ALT for the underlying AES or message digest primitive. Fixes #1798. mbedtls_ctr_drbg_update() -> mbedtls_ctr_drbg_update_ret() mbedtls_hmac_drbg_update() -> mbedtls_hmac_drbg_update_ret()
* Extend ECDH interface to enable alternative implementations.
* Deprecate error codes of the form MBEDTLS_ERR_xxx_INVALID_KEY_LENGTH for ARIA, CAMELLIA and Blowfish. These error codes will be replaced by the more generic per-module error codes MBEDTLS_ERR_xxx_BAD_INPUT_DATA.
* Additional parameter validation checks have been added for the following modules - AES, ARIA, Blowfish, CAMELLIA, CCM, GCM, DHM, ECP, ECDSA, ECDH, ECJPAKE, SHA, Chacha20 and Poly1305, cipher, pk, RSA, and MPI. Where modules have had parameter validation added, existing parameter checks may have changed. Some modules, such as Chacha20 had existing parameter validation whereas other modules had little. This has now been changed so that the same level of validation is present in all modules, and that it is now optional with the MBEDTLS_CHECK_PARAMS flag which by default is off. That means that checks which were previously present by default will no longer be.
New deprecations
* Deprecate mbedtls_ctr_drbg_update() and mbedtls_hmac_drbg_update() in favor of functions that can return an error code.
Bugfix
* Fix for Clang, which was reporting a warning for the bignum.c inline assembly for AMD64 targets creating string literals greater than those permitted by the ISO C99 standard. Found by Aaron Jones. Fixes #482.
* Fix runtime error in mbedtls_platform_entropy_poll() when run through qemu user emulation. Reported and fix suggested by randombit. Fixes #1212.
* Fix an unsafe bounds check when restoring an SSL session from a ticket. This could lead to a buffer overflow, but only in case ticket authentication was broken. Reported and fix suggested by Guido Vranken in #659.
* Add explicit integer to enumeration type casts to example program programs/pkey/gen_key which previously led to compilation failure on some toolchains. Reported by phoenixmcallister. Fixes #2170.
* Clarify documentation of mbedtls_ssl_set_own_cert() regarding the absence of check for certificate/key matching. Reported by Attila Molnar, #507.
* Fix double initialization of ECC hardware that made some accelerators hang.

- Update to version 2.14.1: [bsc#1118727, CVE-2018-19608]
Security
* Fix timing variations and memory access variations in RSA PKCS#1 v1.5
decryption that could lead to a Bleichenbacher-style padding oracle
attack. In TLS, this affects servers that accept ciphersuites based on
RSA decryption (i.e. ciphersuites whose name contains RSA but not
(EC)DH(E)). Discovered by Eyal Ronen (Weizmann Institute), Robert Gillham
(University of Adelaide), Daniel Genkin (University of Michigan),
Adi Shamir (Weizmann Institute), David Wong (NCC Group), and Yuval Yarom
(University of Adelaide, Data61). The attack is described in more detail
in the paper available here: http://cat.eyalro.net/cat.pdf CVE-2018-19608
* In mbedtls_mpi_write_binary(), don't leak the exact size of the number
via branching and memory access patterns. An attacker who could submit
a plaintext for RSA PKCS#1 v1.5 decryption but only observe the timing
of the decryption and not its result could nonetheless decrypt RSA
plaintexts and forge RSA signatures. Other asymmetric algorithms may
have been similarly vulnerable. Reported by Eyal Ronen, Robert Gillham,
Daniel Genkin, Adi Shamir, David Wong and Yuval Yarom.
* Wipe sensitive buffers on the stack in the CTR_DRBG and HMAC_DRBG
modules.
API Changes
* The new functions mbedtls_ctr_drbg_update_ret() and
mbedtls_hmac_drbg_update_ret() are similar to mbedtls_ctr_drbg_update()
and mbedtls_hmac_drbg_update() respectively, but the new functions
report errors whereas the old functions return void. We recommend that
applications use the new functions.
- Version 2.14.0:
Security
* Fix overly strict DN comparison when looking for CRLs belonging to a
particular CA. This previously led to ignoring CRLs when the CRL's issuer
name and the CA's subject name differed in their string encoding (e.g.,
one using PrintableString and the other UTF8String) or in the choice of
upper and lower case. Reported by Henrik Andersson of Bosch GmbH in issue
[#1784].
* Fix a flawed bounds check in server PSK hint parsing. In case the
incoming message buffer was placed within the first 64KiB of address
space and a PSK-(EC)DHE ciphersuite was used, this allowed an attacker
to trigger a memory access up to 64KiB beyond the incoming message buffer,
potentially leading to an application crash or information disclosure.
* Fix mbedtls_mpi_is_prime() to use more rounds of probabilistic testing. The
previous settings for the number of rounds made it practical for an
adversary to construct non-primes that would be erroneously accepted as
primes with high probability. This does not have an impact on the
security of TLS, but can matter in other contexts with numbers chosen
potentially by an adversary that should be prime and can be validated.
For example, the number of rounds was enough to securely generate RSA key
pairs or Diffie-Hellman parameters, but was insufficient to validate
Diffie-Hellman parameters properly.
See "Prime and Prejudice" by by Martin R. Albrecht and Jake Massimo and
Kenneth G. Paterson and Juraj Somorovsky.
Features
* Add support for temporarily suspending expensive ECC computations after
some configurable amount of operations. This is intended to be used in
constrained, single-threaded systems where ECC is time consuming and can
block other operations until they complete. This is disabled by default,
but can be enabled by MBEDTLS_ECP_RESTARTABLE at compile time and
configured by mbedtls_ecp_set_max_ops() at runtime. It applies to the new
xxx_restartable functions in ECP, ECDSA, PK and X.509 (CRL not supported
yet), and to existing functions in ECDH and SSL (currently only
implemented client-side, for ECDHE-ECDSA ciphersuites in TLS 1.2,
including client authentication).
* Add support for Arm CPU DSP extensions to accelerate asymmetric key
operations. On CPUs where the extensions are available, they can accelerate
MPI multiplications used in ECC and RSA cryptography. Contributed by
Aurelien Jarno.
* Extend RSASSA-PSS signature to allow a smaller salt size. Previously, PSS
signature always used a salt with the same length as the hash, and returned
an error if this was not possible. Now the salt size may be up to two bytes
shorter. This allows the library to support all hash and signature sizes
that comply with FIPS 186-4, including SHA-512 with a 1024-bit key.
* Add support for 128-bit keys in CTR_DRBG. Note that using keys shorter
than 256 bits limits the security of generated material to 128 bits.
API Changes
* Add a common error code of `MBEDTLS_ERR_PLATFORM_FEATURE_UNSUPPORTED` for
a feature that is not supported by underlying alternative
implementations implementing cryptographic primitives. This is useful for
hardware accelerators that don't implement all options or features.
New deprecations
* All module specific errors following the form
MBEDTLS_ERR_XXX_FEATURE_UNAVAILABLE that indicate a feature is not
supported are deprecated and are now replaced by the new equivalent
platform error.
* All module specific generic hardware acceleration errors following the
form MBEDTLS_ERR_XXX_HW_ACCEL_FAILED that are deprecated and are replaced
by the equivalent plaform error.
* Deprecate the function mbedtls_mpi_is_prime() in favor of
mbedtls_mpi_is_prime_ext() which allows specifying the number of
Miller-Rabin rounds.
Bugfix
* Fix wrong order of freeing in programs/ssl/ssl_server2 example
application leading to a memory leak in case both
MBEDTLS_MEMORY_BUFFER_ALLOC_C and MBEDTLS_MEMORY_BACKTRACE are set.
Fixes #2069.
* Fix a bug in the update function for SSL ticket keys which previously
invalidated keys of a lifetime of less than a 1s. Fixes #1968.
* Fix failure in hmac_drbg in the benchmark sample application, when
MBEDTLS_THREADING_C is defined. Found by TrinityTonic, #1095
* Fix a bug in the record decryption routine ssl_decrypt_buf()
which lead to accepting properly authenticated but improperly
padded records in case of CBC ciphersuites using Encrypt-then-MAC.
* Fix memory leak and freeing without initialization in the example
program programs/x509/cert_write. Fixes #1422.
* Ignore IV in mbedtls_cipher_set_iv() when the cipher mode is
MBEDTLS_MODE_ECB. Found by ezdevelop. Fixes #1091.
* Zeroize memory used for buffering or reassembling handshake messages
after use.
* Use `mbedtls_platform_zeroize()` instead of `memset()` for zeroization
of sensitive data in the example programs aescrypt2 and crypt_and_hash.
* Change the default string format used for various X.509 DN attributes to
UTF8String. Previously, the use of the PrintableString format led to
wildcards and non-ASCII characters being unusable in some DN attributes.
Reported by raprepo in #1860 and by kevinpt in #468. Fix contributed by
Thomas-Dee.
* Fix compilation failure for configurations which use compile time
replacements of standard calloc/free functions through the macros
MBEDTLS_PLATFORM_CALLOC_MACRO and MBEDTLS_PLATFORM_FREE_MACRO.
Reported by ole-de and ddhome2006. Fixes #882, #1642 and #1706.
Changes
* Removed support for Yotta as a build tool.
* Add tests for session resumption in DTLS.
* Close a test gap in (D)TLS between the client side and the server side:
test the handling of large packets and small packets on the client side
in the same way as on the server side.
* Change the dtls_client and dtls_server samples to work by default over
IPv6 and optionally by a build option over IPv4.
* Change the use of Windows threading to use Microsoft Visual C++ runtime
calls, rather than Win32 API calls directly. This is necessary to avoid
conflict with C runtime usage. Found and fixed by irwir.
* Remember the string format of X.509 DN attributes when replicating
X.509 DNs. Previously, DN attributes were always written in their default
string format (mostly PrintableString), which could lead to CRTs being
created which used PrintableStrings in the issuer field even though the
signing CA used UTF8Strings in its subject field; while X.509 compliant,
such CRTs were rejected in some applications, e.g. some versions of
Firefox, curl and GnuTLS. Reported in #1033 by Moschn. Fix contributed by
Thomas-Dee.
* Improve documentation of mbedtls_ssl_get_verify_result().
Fixes #517 reported by github-monoculture.
* Add MBEDTLS_MPI_GEN_PRIME_FLAG_LOW_ERR flag to mbedtls_mpi_gen_prime() and
use it to reduce error probability in RSA key generation to levels mandated
by FIPS-186-4.
- Version 2.13.1
API Changes
* Extend the platform module with an abstraction mbedtls_platform_gmtime_r()
whose implementation should behave as a thread-safe version of gmtime().
This allows users to configure such an implementation at compile time when
the target system cannot be deduced automatically, by setting the option
MBEDTLS_PLATFORM_GMTIME_R_ALT. At this stage Mbed TLS is only able to
automatically select implementations for Windows and POSIX C libraries.
Bugfix
* Fix build failures on platforms where only gmtime() is available but
neither gmtime_r() nor gmtime_s() are present. Fixes #1907.
- Version 2.13.0
Security
* Fix an issue in the X.509 module which could lead to a buffer overread
during certificate extensions parsing. In case of receiving malformed
input (extensions length field equal to 0), an illegal read of one byte
beyond the input buffer is made. Found and analyzed by Nathan Crandall.
Features
* Add support for fragmentation of outgoing DTLS handshake messages. This
is controlled by the maximum fragment length as set locally or negotiated
with the peer, as well as by a new per-connection MTU option, set using
mbedtls_ssl_set_mtu().
* Add support for auto-adjustment of MTU to a safe value during the
handshake when flights do not get through (RFC 6347, section 4.1.1.1,
last paragraph).
* Add support for packing multiple records within a single datagram,
enabled by default.
* Add support for buffering out-of-order handshake messages in DTLS.
The maximum amount of RAM used for this can be controlled by the
compile-time constant MBEDTLS_SSL_DTLS_MAX_BUFFERING defined
in mbedtls/config.h.
API Changes
* Add function mbedtls_ssl_set_datagram_packing() to configure
the use of datagram packing (enabled by default).
Bugfix
* Fix a potential memory leak in mbedtls_ssl_setup() function. An allocation
failure in the function could lead to other buffers being leaked.
* Fixes an issue with MBEDTLS_CHACHAPOLY_C which would not compile if
MBEDTLS_ARC4_C and MBEDTLS_CIPHER_NULL_CIPHER weren't also defined. #1890
* Fix a memory leak in ecp_mul_comb() if ecp_precompute_comb() fails.
Fix contributed by Espressif Systems.
* Add ecc extensions only if an ecc based ciphersuite is used.
This improves compliance to RFC 4492, and as a result, solves
interoperability issues with BouncyCastle. Raised by milenamil in #1157.
* Replace printf with mbedtls_printf in the ARIA module. Found by
TrinityTonic in #1908.
* Fix potential use-after-free in mbedtls_ssl_get_max_frag_len()
and mbedtls_ssl_get_record_expansion() after a session reset. Fixes #1941.
* Fix a bug that caused SSL/TLS clients to incorrectly abort the handshake
with TLS versions 1.1 and earlier when the server requested authentication
without providing a list of CAs. This was due to an overly strict bounds
check in parsing the CertificateRequest message,
introduced in Mbed TLS 2.12.0. Fixes #1954.
* Fix a miscalculation of the maximum record expansion in
mbedtls_ssl_get_record_expansion() in case of ChachaPoly ciphersuites,
or CBC ciphersuites in (D)TLS versions 1.1 or higher. Fixes #1913, #1914.
* Fix undefined shifts with negative values in certificates parsing
(found by Catena cyber using oss-fuzz)
* Fix memory leak and free without initialization in pk_encrypt
and pk_decrypt example programs. Reported by Brace Stout. Fixes #1128.
* Remove redundant else statement. Raised by irwir. Fixes #1776.
Changes
* Copy headers preserving timestamps when doing a "make install".
Contributed by xueruini.
* Allow the forward declaration of public structs. Contributed by Dawid
Drozd. Fixes #1215 raised by randombit.
* Improve compatibility with some alternative CCM implementations by using
CCM test vectors from RAM.
* Add support for buffering of out-of-order handshake messages.
* Add warnings to the documentation of the HKDF module to reduce the risk
of misusing the mbedtls_hkdf_extract() and mbedtls_hkdf_expand()
functions. Fixes #1775. Reported by Brian J. Murray.

* API Changes
+ Mbed TLS 2.11.0 maintains source code compatibility with the last minor version, Mbed TLS 2.9.0, but extends the interface with additional capabilities. Mbed TLS 2.11.0 modifies the ABI and increases the SOVERSION.
* Bugfix
+ Fixed the cert_write example to handle certificates signed with elliptic curves as well as RSA. Fixes #777 found by dbedev.
+ Fixed the redefinition of _WIN32_WINNT, to avoid overriding a definition used by user applications. Found and fixed by Fabio Alessandrelli.
+ Fixed compilation warnings with the IAR toolchain on 32-bit platforms. Reported by rahmanih in #683.
+ Fixed an issue with MicroBlaze support in bn_mul.h which was causing the build to fail. Found by zv-io. Fixes #1651.
+ Fixed braces in mbedtls_memory_buffer_alloc_status(). Found by sbranden in #552.
+ Added the macro MBEDTLS_X509_MAX_FILE_PATH_LEN that enables the user to configure the maximum length of a file path that can be buffered when calling mbedtls_x509_crt_parse_path(). Fixes #492.
+ Fixed redundant declaration of mbedtls_ssl_list_ciphersuites. Raised by TrinityTonic in #1359.
- Changes for version 2.9.0:
+ Security
+ Fixed an issue in the X.509 module which could lead to a buffer overread during certificate validation. Additionally, the issue could also lead to unnecessary callback checks being made or to some validation checks to be omitted. The overread could be triggered remotely, while the other issues would require a non DER-compliant certificate to be correctly signed by a trusted CA, or a trusted CA with a non DER-compliant certificate. Found by luocm. Fixes #825.
+ Fixed the buffer length assertion in the ssl_parse_certificate_request() function which could lead to an arbitrary overread of the message buffer. The overreads could be caused by receiving a malformed algorithms section which was too short. In builds with debug output, this overread data was output with the debug data.
+ Fixed a client-side bug in the validation of the server's ciphersuite choice which could potentially lead to the client accepting a ciphersuite it didn't offer or a ciphersuite that could not be used with the TLS or DTLS version chosen by the server. This could lead to corruption of internal data structures for some configurations.
* Features
+ Added an option of MBEDTLS_AES_FEWER_TABLES, to dynamically compute smaller AES tables during runtime, thereby reducing the RAM/ROM footprint by ~6KiB. Suggested and contributed by jkivilin.
+ Added initial support for Curve448 (RFC 7748). So far only mbedtls_ecp_mul() and ECDH primitive functions (mbedtls_ecdh_gen_public(), mbedtls_ecdh_compute_shared()) are supported for now. Contributed by Nicholas Wilson.
* API Changes
+ Mbed TLS 2.9.0 maintains source code and binary compatibility with the last minor version, Mbed TLS 2.8.0, but extends the interface with additional capabilities.
+ Extended the API with the function of mbedtls_net_poll() to allow user applications to wait for a network context to become ready before reading or writing.
+ Added the function mbedtls_ssl_check_pending() to the public API to allow a check for whether more more data is pending to be processed in the internal message buffers. This function is necessary to determine the underlying transport when event-driven IO is used.
* Bugfix
+ Fixed a spurious uninitialized variable warning in cmac.c. Fix independently contributed by Brian J Murray and David Brown.
+ Added missing dependencies in test suites that led to build failures in configurations that omit certain hashes or public-key algorithms. Fixes #1040.
+ Fixed a C89 incompatibility issue in benchmark.c. Contributed by Brendan Shanks. Fixes #1353.
+ Added missing dependencies for MBEDTLS_HAVE_TIME_DATE and MBEDTLS_VERSION_FEATURES in some test suites. Contributed by Deomid Ryabkov. Fixes #1299, #1475.
+ Fixed the Makefile build process for building shared libraries on Mac OS X. Fixed by mnacamura.
+ Fixed parsing of PKCS#8 encoded Elliptic Curve keys. Previously Mbed TLS was unable to parse keys which had only the optional parameters field of the ECPrivateKey structure. Found by Jethro Beekman, fixed in #1379.
+ Added an optimisation to return the plaintext data more quickly on unpadded CBC decryption, as stated in the mbedtls_cipher_update() documentation. Contributed by Andy Leiserson.
+ Fixed the overriding and ignoring of return values when parsing and writing to a file in the pk_sign program. Found by kevlut in #1142.
+ Added restrictions to the usage of the error code MBEDTLS_ERR_SSL_WANT_READ to situations where data needs to be fetched from the underlying transport in order to make progress. Previously, this error code was also occasionally returned when unexpected messages were being discarded, ignoring that further messages could potentially already be pending to be processed in the internal buffers; these cases led to deadlocks when event-driven I/O was used. Found and reported by Hubert Mis in #772.
+ Fixed buffer length assertions in the ssl_parse_certificate_request() function which led to a potential one byte overread of the message buffer.
+ Fixed invalid buffer sizes being passed to zlib during record compression and decompression.
+ Raised the soversion of libmbedcrypto to match the soversion of the maintained 2.7 branch. The soversion was increased in Mbed TLS version 2.7.1 to reflect breaking changes in that release, but the increment was missed in 2.8.0 and later releases outside of the 2.7 branch.
* Fri Apr 06 2018 mpluskal@suse.com
- Update to version 2.8.0:
* Security:
+ Defend against Bellcore glitch attacks by verifying the results of RSA private key operations.
+ Fix implementation of the truncated HMAC extension. The previous implementation allowed an offline 2^80 brute force attack on the HMAC key of a single, uninterrupted connection (with no resumption of the session).
+ Reject CRLs containing unsupported critical extensions. Found by Falko Strenzke and Evangelos Karatsiolis.
+ Fix a buffer overread in ssl_parse_server_key_exchange() that could cause a crash on invalid input.
+ Fix a buffer overread in ssl_parse_server_psk_hint() that could cause a crash on invalid input.
* Features:
+ Enable reading encrypted PEM files produced by software that uses PBKDF2-SHA2, such as OpenSSL 1.1. Submitted by Antonio Quartulli, OpenVPN Inc. Fixes #1339
+ Support public keys encoded in PKCS#1 format. #1122
* New deprecations:
+ Compression and crypto don't mix. We don't recommend using compression and cryptography, and have deprecated support for record compression (configuration option MBEDTLS_ZLIB_SUPPORT).
* Bugfix:
+ Fix mbedtls_x509_crt_profile_suiteb, which used to reject all certificates with flag MBEDTLS_X509_BADCERT_BAD_PK even when the key type was correct. In the context of SSL, this resulted in handshake failure. Reported by daniel in the Mbed TLS forum. #1351
+ Fix setting version TLSv1 as minimal version, even if TLS 1 is not enabled. Set MBEDTLS_SSL_MIN_MAJOR_VERSION and MBEDTLS_SSL_MIN_MINOR_VERSION instead of MBEDTLS_SSL_MAJOR_VERSION_3 and MBEDTLS_SSL_MINOR_VERSION_1. #664
+ Fix compilation error on Mingw32 when _TRUNCATE is defined. Use _TRUNCATE only if __MINGW32__ is not defined. Fix suggested by Thomas Glanzmann and Nick Wilson on issue #355
+ Fix memory allocation corner cases in memory_buffer_alloc.c module. Found by Guido Vranken. #639
+ Don't accept an invalid tag when parsing X.509 subject alternative names in some circumstances.
+ Fix a possible arithmetic overflow in ssl_parse_server_key_exchange() that could cause a key exchange to fail on valid data.
+ Fix a possible arithmetic overflow in ssl_parse_server_psk_hint() that could cause a key exchange to fail on valid data.
+ Fix a 1-byte heap buffer overflow (read-only) during private key parsing. Found through fuzz testing.
* Changes
+ Fix tag lengths and value ranges in the documentation of CCM encryption. Contributed by Mathieu Briand.
+ Fix a typo in a comment in ctr_drbg.c. Contributed by Paul Sokolovsky.
+ Remove support for the library reference configuration for picocoin.
+ MD functions deprecated in 2.7.0 are no longer inline, to provide a migration path for those depending on the library's ABI.
+ Use (void) when defining functions with no parameters. Contributed by Joris Aerts. #678
* Thu Mar 08 2018 mpluskal@suse.com
- Use more cmake macros
- Update spec file using spec-cleaner
* Tue Feb 13 2018 kbabioch@suse.com
- Update to version 2.7.0:
- Security
* Fix a heap corruption issue in the implementation of the truncated HMAC
extension. When the truncated HMAC extension is enabled and CBC is used,
sending a malicious application packet could be used to selectively corrupt
6 bytes on the peer's heap, which could potentially lead to crash or remote
code execution. The issue could be triggered remotely from either side in
both TLS and DTLS. (CVE-2018-0488 boo#1080828)
* Fix a buffer overflow in RSA-PSS verification when the hash was too large
for the key size, which could potentially lead to crash or remote code
execution. Found by Seth Terashima, Qualcomm Product Security Initiative,
Qualcomm Technologies Inc. (CVE-2018-0487 boo#1080826)
* Fix buffer overflow in RSA-PSS verification when the unmasked data is all
zeros.
* Fix an unsafe bounds check in ssl_parse_client_psk_identity() when adding
64 KiB to the address of the SSL buffer and causing a wrap around.
* Fix a potential heap buffer overflow in mbedtls_ssl_write(). When the (by
default enabled) maximum fragment length extension is disabled in the
config and the application data buffer passed to mbedtls_ssl_write
is larger than the internal message buffer (16384 bytes by default), the
latter overflows.
* Add a provision to prevent compiler optimizations breaking the time
constancy of mbedtls_ssl_safer_memcmp().
* Ensure that buffers are cleared after use if they contain sensitive data.
Changes were introduced in multiple places in the library.
* Set PEM buffer to zero before freeing it, to avoid decoded private keys
being leaked to memory after release.
* Fix dhm_check_range() failing to detect trivial subgroups and potentially
leaking 1 bit of the private key. Reported by prashantkspatil.
* Make mbedtls_mpi_read_binary() constant-time with respect to the input
data. Previously, trailing zero bytes were detected and omitted for the
sake of saving memory, but potentially leading to slight timing
differences. Reported by Marco Macchetti, Kudelski Group.
* Wipe stack buffer temporarily holding EC private exponent
after keypair generation.
* Fix a potential heap buffer over-read in ALPN extension parsing
(server-side). Could result in application crash, but only if an ALPN
name larger than 16 bytes had been configured on the server.
* Change default choice of DHE parameters from untrustworthy RFC 5114
to RFC 3526 containing parameters generated in a nothing-up-my-sleeve
manner.
- Features
* Add alternative implementation support for CCM and CMAC (MBEDTLS_CCM_ALT,
MBEDTLS_CMAC_ALT). Submitted by Steven Cooreman, Silicon Labs.
* Add support for alternative implementations of GCM, selected by the
configuration flag MBEDTLS_GCM_ALT.
* Add support for alternative implementations for ECDSA, controlled by new
configuration flags MBEDTLS_ECDSA_SIGN_ALT, MBEDTLS_ECDSA_VERIFY_ALT and
MBEDTLS_ECDSDA_GENKEY_AT in config.h.
The following functions from the ECDSA module can be replaced
with alternative implementation:
mbedtls_ecdsa_sign(), mbedtls_ecdsa_verify() and mbedtls_ecdsa_genkey().
* Add support for alternative implementation of ECDH, controlled by the
new configuration flags MBEDTLS_ECDH_COMPUTE_SHARED_ALT and
MBEDTLS_ECDH_GEN_PUBLIC_ALT in config.h.
The following functions from the ECDH module can be replaced
with an alternative implementation:
mbedtls_ecdh_gen_public() and mbedtls_ecdh_compute_shared().
* Add support for alternative implementation of ECJPAKE, controlled by
the new configuration flag MBEDTLS_ECJPAKE_ALT.
* Add mechanism to provide alternative implementation of the DHM module.
- API changes
* Extend RSA interface by multiple functions allowing structure-
independent setup and export of RSA contexts. Most notably,
mbedtls_rsa_import() and mbedtls_rsa_complete() are introduced for setting
up RSA contexts from partial key material and having them completed to the
needs of the implementation automatically. This allows to setup private RSA
contexts from keys consisting of N,D,E only, even if P,Q are needed for the
purpose or CRT and/or blinding.
* The configuration option MBEDTLS_RSA_ALT can be used to define alternative
implementations of the RSA interface declared in rsa.h.
* The following functions in the message digest modules (MD2, MD4, MD5,
SHA1, SHA256, SHA512) have been deprecated and replaced as shown below.
The new functions change the return type from void to int to allow
returning error codes when using MBEDTLS_<MODULE>_ALT.
mbedtls_<MODULE>_starts() -> mbedtls_<MODULE>_starts_ret()
mbedtls_<MODULE>_update() -> mbedtls_<MODULE>_update_ret()
mbedtls_<MODULE>_finish() -> mbedtls_<MODULE>_finish_ret()
mbedtls_<MODULE>_process() -> mbedtls_internal_<MODULE>_process()
- Deprecations
* Deprecate usage of RSA primitives with non-matching key-type
(e.g. signing with a public key).
* Direct manipulation of structure fields of RSA contexts is deprecated.
Users are advised to use the extended RSA API instead.
* Deprecate usage of message digest functions that return void
(mbedtls_<MODULE>_starts, mbedtls_<MODULE>_update,
mbedtls_<MODULE>_finish and mbedtls_<MODULE>_process where <MODULE> is
any of MD2, MD4, MD5, SHA1, SHA256, SHA512) in favor of functions
that can return an error code.
* Deprecate untrustworthy DHE parameters from RFC 5114. Superseded by
parameters from RFC 3526 or the newly added parameters from RFC 7919.
* Deprecate hex string DHE constants MBEDTLS_DHM_RFC3526_MODP_2048_P etc.
Supserseded by binary encoded constants MBEDTLS_DHM_RFC3526_MODP_2048_P_BIN
etc.
* Deprecate mbedtls_ssl_conf_dh_param() for setting default DHE parameters
from hex strings. Superseded by mbedtls_ssl_conf_dh_param_bin()
accepting DHM parameters in binary form, matching the new constants.
- Several bug fixes
* Mon Sep 11 2017 fisiu@opensuse.org
- Update to version 2.6.0:
* Add the functions mbedtls_platform_setup() and mbedtls_platform_teardown()
and the context struct mbedtls_platform_context to perform
platform-specific setup and teardown operations. The macro
MBEDTLS_PLATFORM_SETUP_TEARDOWN_ALT allows the functions to be overridden
by the user in a platform_alt.h file. These new functions are required in
some embedded environments to provide a means of initialising underlying
cryptographic acceleration hardware.
* Reverted API/ABI breaking changes introduced in mbed TLS 2.5.1, to make the
API consistent with mbed TLS 2.5.0. Specifically removed the inline
qualifier from the functions mbedtls_aes_decrypt, mbedtls_aes_encrypt,
mbedtls_ssl_ciphersuite_uses_ec and mbedtls_ssl_ciphersuite_uses_psk. Found
by James Cowgill. #978
* Certificate verification functions now set flags to -1 in case the full
chain was not verified due to an internal error (including in the verify
callback) or chain length limitations.
* With authmode set to optional, the TLS handshake is now aborted if the
verification of the peer's certificate failed due to an overlong chain or
a fatal error in the verify callback.
* Fix authentication bypass in SSL/TLS: when authmode is set to optional,
mbedtls_ssl_get_verify_result() would incorrectly return 0 when the peer's
X.509 certificate chain had more than MBEDTLS_X509_MAX_INTERMEDIATE_CA
(default: 8) intermediates, even when it was not trusted. This could be
triggered remotely from either side. (With authmode set to 'required'
(the default), the handshake was correctly aborted).
Fix for CVE-2017-14032 and boo#1056544.
* Reliably wipe sensitive data after use in the AES example applications
programs/aes/aescrypt2 and programs/aes/crypt_and_hash.
Found by Laurent Simon.
* Mon Jul 10 2017 mpluskal@suse.com
- Update to version 2.5.1:
* Adds hardware acceleration support for the Elliptic Curve Point
module. This has involved exposing parts of the internal
interface to enable replacing the core functions and adding an
alternative, module level replacement to support for enabling
the extension of the interface.
* Adds a new configuration option to mbedtls_ssl_config() to
enable suppressing the CA list in Certificate Request messages.
The default behaviour has not changed, namely every configured
CA's name is included.
* Fixes an unlimited overread of heap-based buffers in
mbedtls_ssl_read(). The issue could only happen client-side
with renegotiation enabled. This could result in a Denial of
Service (such as crashing the application) or information leak.
* Adds exponent blinding to RSA private operations as a
countermeasure against side-channel attacks like the cache
attack described in https://arxiv.org/abs/1702.08719v2.
* Wipes stack buffers in RSA private key operations
(rsa_rsaes_pkcs1_v15_decrypt(), rsa_rsaes_oaep_decrypt()).
* Removes SHA-1 and RIPEMD-160 from the default hash algorithms
for certificate verification. SHA-1 can be turned back on with
a compile-time option if needed.
* Fixes offset in FALLBACK_SCSV parsing that caused TLS server to
fail to detect it sometimes. Reported by Hugo Leisink.
* Tighten parsing of RSA PKCS#1 v1.5 signatures, to avoid a
potential Bleichenbacher/BERserk-style attack.
* Sat Mar 11 2017 mpluskal@suse.com
- Update to version 2.4.2:
* Add checks to prevent signature forgeries for very large messages while
using RSA through the PK module in 64-bit systems. The issue was caused by
some data loss when casting a size_t to an unsigned int value in the
functions rsa_verify_wrap(), rsa_sign_wrap(), rsa_alt_sign_wrap() and
mbedtls_pk_sign(). Found by Jean-Philippe Aumasson.
* Fixed potential livelock during the parsing of a CRL in PEM format in
mbedtls_x509_crl_parse(). A string containing a CRL followed by trailing
characters after the footer could result in the execution of an infinite
loop. The issue can be triggered remotely. Found by Greg Zaverucha,
Microsoft.
* Removed MD5 from the allowed hash algorithms for CertificateRequest and
CertificateVerify messages, to prevent SLOTH attacks against TLS 1.2.
Introduced by interoperability fix for #513.
* Fixed a bug that caused freeing a buffer that was allocated on the stack,
when verifying the validity of a key on secp224k1. This could be
triggered remotely for example with a maliciously constructed certificate
and potentially could lead to remote code execution on some platforms.
Reported independently by rongsaws and Aleksandar Nikolic, Cisco Talos
team. #569 CVE-2017-2784 (boo#1029017)
* Sun Nov 13 2016 mpluskal@suse.com
- Update to version 2.4.0:
* Removes the MBEDTLS_SSL_AEAD_RANDOM_IV configuration option,
because it was not compliant with RFC-5116 and could lead to
session key recovery in very long TLS sessions.
* Fixes potential stack corruption in mbedtls_x509write_crt_der()
and mbedtls_x509write_csr_der() when the signature is copied to
the buffer without checking whether there is enough space in
the destination. The issue cannot be triggered remotely.
* Added support for CMAC for AES and 3DES and AES-CMAC-PRF-128,
as defined by NIST SP 800-38B, RFC-4493 and RFC-4615.
* Added hardware entropy self-test to verify that the hardware
entropy source is functioning correctly.
* Added a script to print build environment information for
diagnostic use in test scripts, which is also now called by
all.sh verification script.
* Added the macro MBEDTLS_X509_MAX_FILE_PATH_LEN that enables the
user to configure the maximum length of a file path that can be
buffered when calling mbedtls_x509_crt_parse_path().
* Added a configuration file config-no-entropy.h that configures
the subset of library features that do not require an entropy
source.
* Added the macro MBEDTLS_ENTROPY_MIN_HARDWARE in config.h. This
allows users to configure the minimum number of bytes for
entropy sources using the mbedtls_hardware_poll() function.

+ Fix issue that caused a crash if invalid curves were passed
to mbedtls_ssl_conf_curves. #373
* Changes
+ On ARM platforms, when compiling with -O0 with GCC, Clang or
armcc5, don't use the optimized assembly for bignum
multiplication. This removes the need to pass
- fomit-frame-pointer to avoid a build error with -O0.
+ Disabled SSLv3 in the default configuration.
+ Fix non-compliance server extension handling. Extensions for
SSLv3 are now ignored, as required by RFC6101.
* Sun Jan 10 2016 mpluskal@suse.com
- Update to 1.3.16
* Fixes a potential double free when
mbedtls_asn1_store_named_data() fails to allocate memory. This
was only used for certificate generation and was not
triggerable remotely in SSL/TLS. boo#961290
* Disables by default MD5 handshake signatures in TLS 1.2 to
prevent the SLOTH (CVE-2015-7575) attack on TLS 1.2 server
authentication (other attacks from the SLOTH paper do not apply
to any version of mbed TLS or PolarSSL). boo#961284
* Fixes an over-restrictive length limit in GCM.
* Fixes a bug in certificate validation that caused valid chains
to be rejected when the first intermediate certificate has a
pathLenConstraint equal to zero.
* Removed potential leak in mbedtls_rsa_rsassa_pkcs1_v15_sign()
* Added config.h option POLARSSL_SSL_ENABLE_MD5_SIGNATURES to
control use of MD5-based signatures for TLS 1.2 handshake
(disabled by default).
* Wed Nov 18 2015 mpluskal@suse.com

Cannot be triggered remotely unless you create X.509 certificates based
on untrusted input or write keys of untrusted origin. Found by Guido
Vranken, Intelworks.
* The X509 max_pathlen constraint was not enforced on intermediate
certificates. Found by Nicholas Wilson, fix and tests provided by
Janos Follath. #280 and #319
* Self-signed certificates were not excluded from pathlen counting,
resulting in some valid X.509 being incorrectly rejected. Found and fix
provided by Janos Follath. #319

overflow of the hostname or session ticket. Found by Guido Vranken,
Intelworks.
* Fix stack buffer overflow in pkcs12 decryption (used by
mbedtls_pk_parse_key(file)() when the password is > 129 bytes. Found by
Guido Vranken, Intelworks. Not triggerable remotely.
* Fix potential buffer overflow in mbedtls_mpi_read_string().
Found by Guido Vranken, Intelworks. Not exploitable remotely in the context
of TLS, but might be in other uses. On 32 bit machines, requires reading a
string of close to or larger than 1GB to exploit; on 64 bit machines, would
require reading a string of close to or larger than 2^62 bytes.
* Fix potential random memory allocation in mbedtls_pem_read_buffer()
on crafted PEM input data. Found and fix provided by Guido Vranken,
Intelworks. Not triggerable remotely in TLS. Triggerable remotely if you

buffer is 512MB or larger on 32-bit platforms. Found by Guido Vranken,
Intelworks. Found by Guido Vranken. Not trigerrable remotely in TLS.
* Fix potential heap buffer overflow in servers that perform client
authentication against a crafted CA cert. Cannot be triggered remotely
unless you allow third parties to pick trust CAs for client auth. Found by
Guido Vranken, Intelworks.
* Fix compile error in net.c with musl libc. Found and patch provided by
zhasha (#278).
* Fix macroization of 'inline' keywork when building as C++. (#279)
* Added checking of hostname length in ssl_set_hostname() to ensure domain
names are compliant with RFC 1035.
- Changes for 1.3.13

tries to continue the handshake after it failed (a misuse of the API).
(Found and patch provided by Fabian Foerg, Gotham Digital Science using afl-fuzz.)
* Add countermeasure against Lenstra's RSA-CRT attack for PKCS#1 v1.5
signatures. (Found by Florian Weimer, Red Hat.)
https://securityblog.redhat.com/2015/09/02/factoring-rsa-keys-with-tls-perfect-forward-secrecy/

caused some handshakes to fail.
* When verifying a certificate chain, if an intermediate certificate is
trusted, no later cert is checked. (suggested by hannes-landeholm)
(#220).
- Changes for 1.3.12
* Increase the minimum size of Diffie-Hellman parameters accepted by the
client to 1024 bits, to protect against Logjam attack.

- Update to 1.3.11:
* Remove bias in mpi_gen_prime (contributed by Pascal Junod).
* Remove potential sources of timing variations (some contributed by Pascal
Junod).
* Options POLARSSL_HAVE_INT8 and POLARSSL_HAVE_INT16 are deprecated.
* Enabling POLARSSL_NET_C without POLARSSL_HAVE_IPV6 is deprecated.
* compat-1.2.h and openssl.h are deprecated.
* ssl_set_own_cert() no longer calls pk_check_pair() since the performance
impact was bad for some users (this was introduced in 1.3.10).
* Move from SHA-1 to SHA-256 in example programs using signatures (suggested
by Thorsten Mühlfelder).
* Remove dependency on sscanf() in X.509 parsing modules.
* Fix compile errors with PLATFORM_NO_STD_FUNCTIONS.
* Fix bug in entropy.c when THREADING_C is also enabled that caused
entropy_free() to crash (thanks to Rafał Przywara).
* Fix memory leak when gcm_setkey() and ccm_setkey() are used more than once
on the same context.
* Fix bug in ssl_mail_client when password is longer that username (found by
Bruno Pape).
* Fix undefined behaviour (memcmp( NULL, NULL, 0 );) in X.509 modules
(detected by Clang's 3.6 UBSan).
* mpi_size() and mpi_msb() would segfault when called on an mpi that is
initialized but not set (found by pravic).
* Fix detection of support for getrandom() on Linux (reported by syzzer) by
doing it at runtime (using uname) rather that compile time.
* Fix handling of symlinks by "make install" (found by Gaël PORTAY).
* Fix potential NULL pointer dereference (not trigerrable remotely) when
ssl_write() is called before the handshake is finished (introduced in
1.3.10) (first reported by Martin Blumenstingl).
* Fix bug in pk_parse_key() that caused some valid private EC keys to be
rejected.
* Fix bug in Via Padlock support (found by Nikos Mavrogiannopoulos).
* Fix thread safety bug in RSA operations (found by Fredrik Axelsson).
* Fix hardclock() (only used in the benchmarking program) with some versions
of mingw64 (found by kxjhlele).
* Fix potential unintended sign extension in asn1_get_len() on 64-bit
platforms.
* Fix potential memory leak in ssl_set_psk() (found by Mansour Moufid).
* Fix compile error when POLARSSL_SSL_DISABLE_RENEGOTATION and
POLARSSL_SSL_SSESSION_TICKETS where both enabled in config.h (introduced in
1.3.10).
* Add missing extern "C" guard in aesni.h (reported by amir zamani).
* Add missing dependency on SHA-256 in some x509 programs (reported by
Gergely Budai).
* Fix bug related to ssl_set_curves(): the client didn't check that the curve
picked by the server was actually allowed.
- Drop getrandom-syscall-fallback.patch: fixed upstream.
* Wed Apr 01 2015 schwab@suse.de
- getrandom-syscall-fallback.patch: Fall back to /dev/urandom if getrandom
syscall is not implemented.
* Fri Mar 27 2015 mpluskal@suse.com

* Sun Mar 15 2015 mpluskal@suse.com
- Rename to mbedtls
- Use cmake macro for building
- Update to 1.3.10
* NULL pointer dereference in the buffer-based allocator when the buffer is
full and polarssl_free() is called (found by Mark Hasemeyer)
(only possible if POLARSSL_MEMORY_BUFFER_ALLOC_C is enabled, which it is
not by default).
* Fix remotely-triggerable uninitialised pointer dereference caused by
crafted X.509 certificate (TLS server is not affected if it doesn't ask for a
client certificate) (found using Codenomicon Defensics).
* Fix remotely-triggerable memory leak caused by crafted X.509 certificates
(TLS server is not affected if it doesn't ask for a client certificate)
(found using Codenomicon Defensics).
* Fix potential stack overflow while parsing crafted X.509 certificates
(TLS server is not affected if it doesn't ask for a client certificate)
(found using Codenomicon Defensics).
* Fix timing difference that could theoretically lead to a
Bleichenbacher-style attack in the RSA and RSA-PSK key exchanges
(reported by Sebastian Schinzel).
* Add support for FALLBACK_SCSV (draft-ietf-tls-downgrade-scsv).
* Add support for Extended Master Secret (draft-ietf-tls-session-hash).
* Add support for Encrypt-then-MAC (RFC 7366).
* Add function pk_check_pair() to test if public and private keys match.
* Add x509_crl_parse_der().
* Add compile-time option POLARSSL_X509_MAX_INTERMEDIATE_CA to limit the
length of an X.509 verification chain.
* Support for renegotiation can now be disabled at compile-time
* Support for 1/n-1 record splitting, a countermeasure against BEAST.
* Certificate selection based on signature hash, prefering SHA-1 over SHA-2
for pre-1.2 clients when multiple certificates are available.
* Add support for getrandom() syscall on recent Linux kernels with Glibc or
a compatible enough libc (eg uClibc).
* Add ssl_set_arc4_support() to make it easier to disable RC4 at runtime
while using the default ciphersuite list.
* Added new error codes and debug messages about selection of
ciphersuite/certificate.
* Tue Jan 20 2015 fisiu@opensuse.org
- Add polarssl-CVE-2015-1182.patch: Remote attack using crafted certificates:
