This is a rebase of ghostscript package, to address several security issues :
CVE-2016-7977 -
.libfile does not honor -dSAFER
[CVE-2013-5653](https://bugzilla.redhat.com/show_bug.cgi ?id=1380327) - *getenv and filenameforall ignore
-dSAFER*
[CVE-2016-7976](https://bugzilla.redhat.com/show_bug.cgi ?id=1382294) - *various userparams allow %pipe% in paths, allowing remote shell*
[CVE-2016-7978](https://bugzilla.redhat.com/show_bug.cgi ?id=1382300) - *reference leak in .setdevice allows use-after-free and remote code*
[CVE-2016-7979](https://bugzilla.redhat.com/show_bug.cgi ?id=1382305) - *Type confusion in .initialize_dsc_parser allows remote code execution*
----------- #### INFORMATION FOR FEDORA PACKAGERS & MAINTAINERS :
ghostscript has been rebased to latest upstream version (9.20).
Rebase notes :
no API/ABI changes between versions 9.16 -> 9.20 according to upstream
OpenJPEG support has been retained
ijs-config custom tool from upstream has been
removed (by upstream) (pkg-config is used by default now instead, see [commit 0c176a9](http://git.ghostscript.com/?p=ghostpdl.git;h=0c 176a91d53c85cda))
some patches were updated to ‘git format-patch’ format & renamed
rest of the patches were deleted (irrelevant for current version), mostly because upstream has fixed those issues in some way
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
