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? [0]: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=840451 [1]: http://git.savannah.gnu.org/cgit/ghostscript.git/tree/psi/zht2.cWDYT? Perhaps a new release incorporating the fixes is in order?FYI, I ported the upstream patches to GNU ghostscript for GNU Guix.
