- The version upgrade to 9.52 fixes in particular
CVE-2020-12268: jbic2dec: heap-based buffer overflow
in jbig2_image_compose (bsc#1170603)
- Version upgrade to 9.52
Highlights in this release include:
* The 9.52 release replaces the 9.51 release after a problem
was reported with 9.51 which warranted the quick turnaround.
Thus, like 9.51, 9.52 is primarily a maintenance release,
consolidating the changes we introduced in 9.50.
* IMPORTANT: We have forked LittleCMS2 into LittleCMS2mt
(the "mt" indicating "multi-thread").
LCMS2 is not thread-safe, and cannot be made thread-safe
without breaking the ABI. Our fork will be thread-safe and
include performance enhancements (these changes have all
been offered and rejected upstream). We will maintain
compatibility between Ghostscript and LCMS2 for a time,
but not in perpetuity. If there is sufficient interest,
our fork will be available as its own package separately
from Ghostscript (and MuPDF).
* The usual round of bug fixes, compatibility changes,
and incremental improvements.
Incompatible changes:
* New option -dALLOWPSTRANSPARENCY: The transparency compositor
(and related features), whilst we are improving it, remains
sensitive to being driven correctly, and incorrect use
can have unexpected/undefined results. Hence, as part of
improving security, we limited access to these operators,
originally using the -dSAFER feature. As we made "SAFER"
the default mode, that became unacceptable, hence the
new option -dALLOWPSTRANSPARENCY which enables access
to the operators, cf.
https://www.ghostscript.com/doc/9.52/Use.htm#ALLOWPSTRANSPARENCY
For a release summary see:
https://www.ghostscript.com/doc/9.52/News.htm
For details see the News.htm and History9.htm files.
- Version upgrade to 9.51
Highlights in this release include:
* 9.51 is primarily a maintainance release, consolidating
the changes we introduced in 9.50.
* We have continued our work on code hygiene for this release,
with a focus on the static analysis tool Coverity
(from Synopsys, Inc) and we are now maintaining a policy of
zero Coverity issues in the Ghostscript/GhostPDL source base.
* IMPORTANT: In consultation with a representative of
OpenPrinting (http://www.openprinting.org/) it is our
intention to deprecate and, in the not distant future,
remove the OpenPrinting Vector/Raster Printer Drivers
(that is, the opvp and oprp devices).
If you rely on either of these devices, please get in touch
with us (i.e. Ghostscript upstream), so we can discuss your
use case, and revise our plans accordingly.
* We (i.e. Ghostscript upstream) are in the process of forking
LittleCMS, cf. the other release notes entries below.
* The usual round of bug fixes, compatibility changes,
and incremental improvements.
For a release summary see:
https://www.ghostscript.com/doc/9.51/News.htm
For details see the News.htm and History9.htm files.
- Version upgrade to 9.50
Highlights in this release include:
* The change to version 9.50 follows recognition
of the extent and importance of the file access control
redesign/reimplementation outlined below.
* The file access control capability (enable with -dSAFER)
has been completely rewritten, with a ground-up rethink
of the design. For more details, see: "SAFER" at
https://www.ghostscript.com/doc/9.50/Use.htm#Safer
* It is important to note that -dSAFER now only enables the
file access controls, and no longer applies restrictions
to standard Postscript functionality (specifically,
restrictions on setpagedevice). If your application relies
on these Postscript restrictions, see "OLDSAFER" at
https://www.ghostscript.com/doc/9.50/Use.htm#OldSafer
and please get in touch, as we do plan to remove those
Postscript restrictions unless we have reason not to.
IMPORTANT: File access controls are now enabled by default.
In order to run Ghostscript without these controls,
see "NOSAFER" at
https://www.ghostscript.com/doc/9.50/Use.htm#NoSafer
* We (i.e. Ghostscript upstream) are in the process of forking
LittleCMS, cf. the other release notes entries below.
* The usual round of bug fixes, compatibility changes,
and incremental improvements.
Incompatible changes:
* There are a couple of subtle incompatibilities between the old
and new SAFER implementations. Firstly, as mentioned above,
SAFER now leaves standard Postcript functionality unchanged
(except for the file access limitations). Secondly, the
interaction with save/restore operations, see "SAFER" at
https://www.ghostscript.com/doc/9.50/Use.htm#Safer
* The following is not strictly speaking new to 9.50,
as not much has changed since 9.27 in this area,
but for those who don't upgrade with every release:
The process of "tidying" the Postscript name space should have
removed only non-standard and undocumented operators.
Nevertheless, it is possible that any integrations or utilities
that rely on those non-standard and undocumented operators
may stop working, or may change behaviour.
If you encounter such a case, please contact us
(i.e. Ghostscript upstream, either the #ghostscript IRC channel
or the gs-devel mailing list would be best), and we'll work
with you to either find an alternative solution or return the
previous functionality, if there is genuinely no other option.
One case we know this has occurred is GSView 5 (and earlier).
GSView 5 support for PDF files relied upon internal use only
features which are no longer available. GSView 5 will still
work as previously for Postscript files. For PDF files,
users are encouraged to look at MuPDF https://www.mupdf.com/

* Thu Apr 04 2019 jsmeix@suse.de
- Version upgrade to 9.27
Highlights in this release include:
* We (i.e. Ghostscript upstream) have extensively cleaned up
the Postscript name space: removing access to internal and/or
undocumented Postscript operators, procedures and data.
This has benefits for security and maintainability.
Incompatible changes:
The process of "tidying" the Postscript name space should
have removed only non-standard and undocumented operators.
Nevertheless, it is possible that any integrations or
utilities that rely on those non-standard and undocumented
operators may stop working, or may change behaviour.
If you encounter such a case, please contact us (i.e.
Ghostscript upstream) - (either the #ghostscript IRC channel,
or the gs-devel mailing list would be best), and we'll work
with you to either find an alternative solution.
* Fontmap can now reference invidual fonts in a TrueType
Collection for font subsitution. Previously, a Fontmap entry
could only reference a TrueType collection and use the default
(first) font.
Now, the Fontmap syntax allows for specifying a specific index
in a TTC. See the comments at the top of (the default)
Fontmap.GS for details.
* The usual round of bug fixes, compatibility changes,
and incremental improvements.
IMPORTANT: It is our intention, within the next 12 months
(ideally sooner, in time for the next release) to make SAFER
the default mode of operation. For many users this will have
no effect, since they use SAFER explicitly, but some niche
uses which rely on SAFER being disabled may need to start
explicitly adding the "-dNOSAFER" option.
IMPORTANT: We (i.e. Ghostscript upstream) are in the process of
forking LittleCMS. LCMS2 is not thread safe, and cannot be made
thread safe without breaking the ABI. Our fork will be thread
safe, and include performance enhancements (these changes have
all be been offered and rejected upstream). We will maintain
compatibility between Ghostscript and LCMS2 for a time, but not
in perpetuity. Our fork will be available as its own package
separately from Ghostscript (and MuPDF).

https://bugzilla.suse.com/show_bug.cgi?id=1108027 bnc#1108027
Regarding what the above "should fix" means:
PostScript is a general purpose Turing-complete programming
language (cf. https://en.wikipedia.org/wiki/PostScript)
that supports in particular file access on the system disk.
When Ghostscript processes PostScript it runs a PostScript
program as the user who runs Ghostscript.
When Ghostscript processes an arbitrary PostScript file,
the user who runs Ghostscript runs an arbitrary program
which can do anything on the system where Ghostscript runs
that this user is allowed to do on that system.
To make it safer when Ghostscript runs a PostScript program
the Ghostscript command line option '-dSAFER' disables
certain file access functionality, for details see
/usr/share/doc/ghostscript/9.25/Use.htm
Its name 'SAFER' says everything: It makes it 'safer'
to let Ghostscript run a PostScript program,
but it does not make it completely safe.
In theory software is safe against misuse (i.e. has no bugs).
In practice there is an endless sequence of various kind of
security issues (i.e. software can be misused to do more than
what is intended) that get fixed issue by issue ad infinitum.
In the end all that means:
In practice the user who runs Ghostscript must not let it
process arbitrary PostScript files from untrusted origin.
In particular Ghostscript is usually run when printing
documents (with the '-dSAFER' option set), see the part about
"It is crucial to limit access to CUPS to trusted users" in
https://en.opensuse.org/SDB:CUPS_and_SANE_Firewall_settings
* Thu Sep 13 2018 jsmeix@suse.de
- Version upgrade to 9.25rc1 (first release candidate for 9.25).
Highlights in this release include:
* This release fixes problems with argument handling, some
unintended results of the security fixes to the SAFER file
access restrictions (specifically accessing ICC profile files),
and some additional security issues over the 9.24 release.
* Security issues have been the primary focus of this release,
including solving several (well publicised) real
and potential exploits.
PLEASE NOTE:
We (i.e. Ghostscript upstream) strongly urge users to upgrade
to this latest release to avoid these issues.
* Avoid that ps2epsi fails with
'Error: /undefined in --setpagedevice--'
Recent changes required to harden SAFER mode mean that
it is no longer possible to run ps2epsi in SAFER mode,
because it relies upon unsafe Ghostscript non-standard
extension operators.
Removing SAFER and DELAYSAFER, and the code to reset SAFER,
allow ps2epsi to run as well as it ever did (ie badly).
This program (i.e. ps2epsi) should now be considered unsafe,
you should not use it on untrusted PostScript programs.
Likely we (i.e. Ghostscript upstream) will deprecate and
remove this program in future.
For details see the News.htm and History9.htm files.
Regarding installing packages (in particular release candidates)
from the openSUSE build service development project "Printing"
see https://build.opensuse.org/project/show/Printing
* Thu Sep 13 2018 jsmeix@suse.de
- Version upgrade to 9.24
Highlights in this release include:
* Security issues have been the primary focus of this release,
including solving several (well publicised)
real and potential exploits.
PLEASE NOTE:
We (i.e. Ghostscript upstream) strongly urge users to upgrade
to this latest release to avoid these issues.
* As well as Ghostscript itself, jbig2dec has had a significant
amount of work improving its robustness in the face of
out specification files.
* IMPORTANT: We (i.e. Ghostscript upstream) are in the process
of forking LittleCMS. LCMS2 is not thread safe, and cannot
be made thread safe without breaking the ABI. Our fork
will be thread safe, and include performance enhancements
(these changes have all be been offered and rejected upstream).
We will maintain compatibility between Ghostscript and LCMS2
for a time, but not in perpetuity. Our fork will be available

* Thu Mar 22 2018 jsmeix@suse.de
- Version upgrade to 9.23
Highlights in this release include:
* Ghostscript now has a family of 'pdfimage' devices
(pdfimage8, pdfimage24 and pdfimage32) which produce
rendered output wrapped up as an image in a PDF.
Additionally, there is a 'pclm' device which
produces PCLm format output.
* There is now a ColorAccuracy parameter allowing the user
to decide between speed or accuracy in ICC color transforms.
* JPEG Passthrough: devices which support it can now receive
the 'raw' JPEG stream from the interpreter.
The main use of this is the pdfwrite/ps2write family of devices
that can now take JPEG streams from the input file(s) and write
them unchanged to the output (thus avoiding additional
quantization effects).
* PDF transparency performance improvements
* IMPORTANT: We (i.e. Ghostscript upstream) are in the process
of forking LittleCMS.
LCMS2 is not thread safe, and cannot be made thread safe
without breaking the ABI. Our fork will be thread safe,
and include performance enhancements (these changes have all
be been offered and rejected upstream). We will maintain
compatibility between Ghostscript and LCMS2 for a time,
but not in perpetuity. Our fork will be available as its own
package separately from Ghostscript (and MuPDF).
* We have continued the focus on code hygiene in this release
cleaning up security issues, ignored return values,
and compiler warnings.
* The usual round of bug fixes, compatibility changes,
and incremental improvements.
Incompatible changes
* The planned device API tidy has, unfortunately, been
indefinitely postponed, until appropriate resources
are available.

See also the entries below since "Version upgrade to 9.22"
(boo#1082896 and boo#1074266).
* Fri Mar 16 2018 jsmeix@suse.de
- For now use lcms2 from SUSE because that is what currently
Ghostscript upstream recommends according to
https://ghostscript.com/pipermail/gs-devel/2018-March/010061.html
because since Ghostscript 9.23rc1 there is no longer lcms2
in Ghostscript but now it is lcms2art which is the beginning
of a lcms2 fork, see News.htm that reads in particular
"LCMS2 is not thread safe ... Our fork will be thread safe ...
We will maintain compatibility between Ghostscript and LCMS2
for a time, but not in perpetuity", see also
https://bugzilla.opensuse.org/show_bug.cgi?id=1082896#c14
- On SLE11 and on SLE12-SP1 there is liblcms2-2-2.5
which is too old so that configure fails there with
configure: error: lcms2 not found, or too old
but there is no configure option to build it without lcms2
so that for SLE11 and SLE12-SP1 it is built with
the lcms2art in Ghostscript.
- ppc64le-support.patch is no longer needed because it only
contained a fix for lcms2art/include/lcms2art.h in Ghostscript
but currently lcms2 from SUSE is used instead (see above).
- Do no longer require any fonts packages in particular
neither require ghostscript-fonts-std because the PostScript
Base35 fonts are provided by Ghostscript (in 'Resource')
nor require ghostscript-fonts-other (provides Bitream Charter,
Adobe Utopia, URW Antiqua, URW Grotesq and Hershey fonts where
all but the last are also provided by texlive-<name>-fonts) and
those fonts are not required for PostScript compliance, see
https://bugzilla.opensuse.org/show_bug.cgi?id=1082896#c13
* Thu Mar 15 2018 jsmeix@suse.de
- Version upgrade to 9.23rc1 (first release candidate for 9.23).

Regarding installing packages (in particular release candidates)
from the openSUSE build service development project "Printing"
see https://build.opensuse.org/project/show/Printing
- Adapted ppc64le-support.patch: In Ghostscript 9.23 there is now
lcms2art/include/lcms2art.h (instead of lcms2/include/lcms2.h).
- ghostscript-fix-debug-use.patch is no longer needed
because the issue is fixed in the upstream sources.
- fix_ln_docdir_gsdatadir.patch avoids
"base/unixinst.mak:162: recipe for target 'install-doc' failed"
- Adapted spec file to the new Ghostscript upstream documentation
directory /usr/share/doc/ghostscript/9.23/
* Wed Feb 28 2018 stefan.bruens@rwth-aachen.de

- Remove --disable-omni switch, has been removed in GS 9.20
- Keep patch ordering in full/mini consistent
- Remove patch backup files to avoid packaging
* Tue Feb 27 2018 novell@mirell.de

* Wed Nov 29 2017 jsmeix@suse.de
- Version upgrade to 9.22.
For details see the News.htm and History9.htm files.
Highlights in this release include:
* Ghostscript can now consume and produce (via the pdfwrite
device) PDF 2.0 compliant files.
* The main focus of this release has been security and code
cleanliness. Hence many AddressSanitizer, Valgrind and
Coverity issues have been addressed.
* The usual round of bug fixes, compatibility changes,
and incremental improvements.
Incompatible changes
* The planned device API tidy (still!) did not happen for
this release, due to time pressures, but we still intend
to undertake the following: We plan to somewhat tidy up
the device API. We intend to remove deprecated device procs
(methods/function pointers) and change the device API
so every device proc takes a graphics state parameter
(rather than the current scheme where only a very few procs
take an imager state parameter). This should serve as notice
to anyone maintaining a Ghostscript device outside the
canonical source tree that you may (probably will) need
to update your device(s) when these changes happen.
Devices using only the non-deprecated procs should be
trivial to update.
- Up to 9.22rc1 it "just built" for all openSUSE versions but
since 9.22rc2 the libijs part does no longer buid for any
released openSUSE version where if fails with messages like
libtool: Version mismatch error.
This is libtool 2.4.6 Debian-2.4.6-2, but the
definition of this LT_INIT comes from libtool 2.4.2.
You should recreate aclocal.m4 with macros from
libtool 2.4.6 Debian-2.4.6-2 and run autoconf again.
Makefile: recipe for target 'ijs.lo' failed
so that currently it only builds for Tumbleweed/Factory.
Presumably it is not too complicated to make it build again
also for released openSUSE versions but currently I have
less than zero energy to fix such "latest breaking changes"
so that for now Ghostscript 9.22 is only provided for
openSUSE Tumbleweed/Factory and the upcoming SLE15/Leap15.

(bsc#1032114)
* Mon Apr 10 2017 jsmeix@suse.de
- Version upgrade to 9.21.
For details see the News.htm and History9.htm files.
Highlights in this release include:
* pdfwrite now preserves annotations from
input PDFs (where possible).
* The GhostXPS interpreter now provides the pdfwrite device
with the data it requires to emit a ToUnicode CMap: thus
allowing fully searchable PDFs to be created from XPS
input (in the vast majority of cases).
* Ghostscript now allows the default color space
for PDF transparency blends.
* The Ghostscript/GhostPDL configure script now has much
better/fuller support for cross compiling.
* The tiffscaled and tiffscaled4 devices can now
use ETS (Even Tone Screening)
* The toolbin/pdf_info.ps utility can now emit
the PDF XML metadata.
* Ghostscript has a new scan converter available
(currently optional, but will become the default in a near
future release). It can be enabled by using the command line
option: '-dSCANCONVERTERTYPE=2'. This new implementation
provides vastly improved performance with large and complex
paths.
* The usual round of bug fixes, compatibility changes,
and incremental improvements.
Incompatible changes:
* The planned device API tidy (still!) did not happen for
this release, due to time pressures, but we still intend
to undertake the following: We plan to somewhat tidy up
the device API. We intend to remove deprecated device
procs (methods/function pointers) and change the device API

- Version upgrade to 9.20. Purely a maintenance release.
For details see the News.htm and History9.htm files.
Highlights in this release include:
* The usual round of bug fixes, compatibility changes,
and incremental improvements.
Incompatible changes:
* The planned device API tidy did not happen for this release,
due to time pressures, but we still intend to undertake the
following: We plan to somewhat tidy up the device API.
We intend to remove deprecated device procs
(methods/function pointers) and change the device API

from the openSUSE build service development project "Printing"
see https://build.opensuse.org/project/show/Printing
* Wed Mar 23 2016 jsmeix@suse.de
- Version upgrade to 9.19. Mainly a maintenance release.
For details see the News.htm and History9.htm files.
Highlights in this release include:
* Metadata pdfmark is now implemented. This allows the user
to specify an XMP stream which will be written to the
Catalog of the PDF file. A new pdfmark 'Ext_Metadata' has
been defined. This takes a string parameter which contains
XML to be add to the XMP normally created by pdfwrite.
See "pdfwrite pdfmark extensions" for more information.
* An experimental, rudimentary raster trapping implementation
has been added to the Ghostscript graphics library.
See "Trapping" for details.
Incompatible changes:
* (Minor) API change: copy_alpha now supports 8 bit depth
(as well as the previous 2 and 4).
* The gs man pages are woefully out of date and basically
unmaintained. With the release following 9.19, we intend
to replace their contents with a very limited summary
of (unlikely to ever change aspects of) calling
Ghostscript, and a pointer to the (maintained) HTML
documentation. That is, unless a volunteer is willing
to update, and commit to maintaining the man pages.
* ijs-config is no longer provided
Planned incompatible changes:
* We plan (ideally for the release following 9.19) to somewhat
tidy up the device API. We plan to remove deprecated device
procs (methods/function pointers). We also intend to merge
the imager state and graphics state (thus eliminating the
imager state), and change the device API so every device proc
takes a graphics state parameter (rather than the current
scheme where only a very few procs take an imager state
parameter). This should serve as notice to anyone maintaining
a Ghostscript device outside the canonical source tree that
you may (probably will) need to update your device(s) when
these changes happen. Devices using only the non-deprecated
procs should be trivial to update.
- fix_make_install.patch fixes and
add_brackets_for_old_autoconf.patch are no longer needed
because both issues are fixed in the upstream sources.
* Fri Mar 18 2016 jsmeix@suse.de
- Version upgrade to 9.19rc1 (first release candidate for 9.19).
For details see the News.htm and History9.htm files.

- fix_ijs_and_x11_for_FirstPage_and_LastPage.patch is no longer
needed because it is fixed in the upstream sources.
- install_gserrors.h.patch is no longer needed because it is fixed
in the upstream sources.
* Wed Nov 18 2015 schwab@suse.de
- Do not use library sources for freetype jpeg libpng tiff zlib
from the Ghostscript upstream tarball because we prefer to use
for long-established standard libraries the ones from SUSE
in particular to automatically get SUSE security updates
for standard libraries.
In contrast we use e.g. lcms2 from the Ghostscript upstream
tarball because this one is specially modified to work with
Ghostscript so that we cannot use lcms2 from SUSE.
- remove-zlib-h-dependency.patch removes dependency on zlib/zlib.h
in makefiles as we do not use the zlib sources from the
Ghostscript upstream tarball.
* Thu Nov 05 2015 jsmeix@suse.de
- An incompatible change appeared when building other software
with Ghostscript 9.18.
Since version 9.18 Ghostscript does no longer provide
e_<SomeError> (e.g. e_NeedInput) in its header files
(gserrors.h and ierrors.h).
When building other software with Ghostscript 9.18
gs_error_<SomeError> (e.g. gs_error_NeedInput)
must be used, see boo#953149 and
http://bugs.ghostscript.com/show_bug.cgi?id=696317
* Fri Oct 30 2015 jsmeix@suse.de
- install_gserrors.h.patch installs gserrors.h to fix
http://bugs.ghostscript.com/show_bug.cgi?id=696301
because without gserrors.h several other packages fail to build
(in particular texlive, libspectre, gimp,...).
* Mon Oct 12 2015 jsmeix@suse.de
- fix_ijs_and_x11_for_FirstPage_and_LastPage.patch
fixes the Ghostscript device ijs and the x11* devices
so that they also work when -dFirstPage/-dLastPage is used,
see http://bugs.ghostscript.com/show_bug.cgi?id=696246
* Tue Oct 06 2015 jsmeix@suse.de
- Version upgrade to 9.18. A maintenance release.
There are no recorded incompatible changes (as of this writing).
Highlights in this release include:
* A substantial revision of the build system and GhostPDL
directory structure. Ghostscript-only users should
not be affected by this change.
* A new method of internally inserting devices into the device
chain has been developed, named "device subclassing".
This allows suitably written devices to be more easily and
consistently as "filter" devices.
The first fruit of this is a new implementation of
the "-dFirstPage"/"-dLastPage" feature which functions
a device filter in the Ghostscript graphics library, meaning
it works consistently with all input languages.
* Plus the usual round of bug fixes, compatibility changes,
and incremental improvements.
