This is tagged as version 9.26a in the ghostpdl repo, but unfortunately
there are no tarballs released with that version number so far. We'll
continue calling this version 9.26 for now for simplicity's sake (and we
can switch to 9.26a and remove the patch when it's properly released).
Fixes #58262
Fixes #58089
GS ships with a fork of lcms2 ("lcms2mt"), but the ABI separation
between the fork and the original seems insufficient. If libgs is linked
alongside liblcms2 (for example, this is the case with imagemagick) then
it will call into the original library instead of the fork, causing
segfaults.
Follow the example of both Arch and Debian in this regard -- they both
use the systemwide lib instead of the fork.
I previously didn't update the hash, so was still building ghostscript-9.24
(which explained why docs were still from 9.24)
The ICC profile validation patch from #47937 is included in 9.25, so we
can strip it from the list of patches.

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 recent 9.24 release.
CVE-2018-16802
CVE-2018-17183
Note: The ps2epsi utility does not, and cannot call Ghostscript with the -dSAFER command line option. It should never be called with input from untrusted sources.
Security issues have been the primary focus of this release, including solving several (well publicised) real and potential exploits.
PLEASE NOTE: We 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 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).
The usual round of bug fixes, compatibility changes, and incremental improvements.
The $doc stuff needed changes, probably because of ghostscript newly
reacting to some configure flags that stdenv passes.
- share/ghostscript/9.22/doc was an ugly location for documentation,
and I didn't like their new share/ghostscript/9.24 either,
so that got changed to share/doc/ghostscript/9.24
- their process no longer installs examples, apparently,
but I don't expect that would be any problem for us
There are also non-security changes in the releases. /cc #32459.
Printing test OK, and I tested work with some postscript files.
I also fixed the license - it was changed in 2013 :-/
* pkgs: refactor needless quoting of homepage meta attribute
A lot of packages are needlessly quoting the homepage meta attribute
(about 1400, 22%), this commit refactors all of those instances.
* pkgs: Fixing some links that were wrongfully unquoted in the previous
commit
* Fixed some instances
This reverts commit 13fab57d12.
Hopefully fixes the printing tests at
http://hydra.nixos.org/build/14952070/log/raw ; if not, it's probably
gutenprint although I doubt:
client# lp: Unsupported document-format "application/pdf".
