GNU Ghostscript is also affected at least by CVE-2016-8602. Looking at the patch in this bug report[0] and the source[1], one can see that the vulnerable lines are present in GNU Ghostscript.

What should we do now? I don't know the relationship between GNU Ghostscript and "upstream" Ghostscript. Can anyone explain why GNU offers its own distribution? We can try cherry-picking the upstream commits that fix each of these bugs [0]. Hopefully they apply to our older Ghostscript version. If the resulting package's ABI is compatible to our current package, we can apply it with a graft on the master branch. We should also apply these patches to the ghostscript package on core-updates. Do you want to try it?
