Version: 2.38 Vendor: openSUSE
Release: 7.1 Build date: Wed Dec 6 23:55:36 2023

Summary: Standard Shared Libraries (from the GNU C Library)
The GNU C Library provides the most important standard libraries used
by nearly all programs: the standard C library, the standard math
library, and the POSIX thread library. A system is not functional
without these libraries.

      applications compiling with glibc and gcc 12 and later
    Deprecated and removed features, and other changes affecting compatibility:
    * On x86-64, the LD_PREFER_MAP_32BIT_EXEC environment variable support
      has been removed since the first PT_LOAD segment is no longer executable
      due to defaulting to -z separate-code

      incompatible with GDB
    * Intel MPX support (lazy PLT, profile, and LD_AUDIT) has been removed

      been removed

      removal of the LD_TRACE_PRELINKING, and LD_USE_LOAD_BIAS, environment
      variables and their functionality in the dynamic loader
    Changes to build and runtime requirements:
    * The audit module interface version LAV_CURRENT is increased to enable
      proper bind-now support
    * The audit interface on aarch64 is extended to support both the indirect
      result location register (x8) and NEON Q register
    Security related changes:
    * CVE-2022-23219: Passing an overlong file name to the clnt_create
      legacy function could result in a stack-based buffer overflow when
      using the "unix" protocol
    * CVE-2022-23218: Passing an overlong file name to the svcunix_create
      legacy function could result in a stack-based buffer overflow
    * CVE-2021-3998: Passing a path longer than PATH_MAX to the realpath
      function could result in a memory leak and potential access of
      uninitialized memory
    * CVE-2021-3999: Passing a buffer of size exactly 1 byte to the getcwd
      function may result in an off-by-one buffer underflow and overflow
      when the current working directory is longer than PATH_MAX and also
      corresponds to the / directory through an unprivileged mount

    * The new --help option of the dynamic linker provides usage and
      information and library search path diagnostics.

    * Using weak references to libpthread functions such as pthread_create
      or pthread_key_create to detect the singled-threaded nature of a
