Notes
[wheezy] - ghostscript <no-dsa> (Not directly reproducible, to re-evaluate once the upstream fix is known)
https://bugs.ghostscript.com/show_bug.cgi?id=697459

I got the reproducer file from the bug submitter and tried to reproduce it.
Results are the following: sid/stretch with 9.20~dfsg-3 are
affected, it even segfaults. But with wheezy 9.05~dfsg-6.3+deb7u2
and jessie 9.06~dfsg-2+deb8u4, we have no segfault and valgrind
reports no buffer overrun. -- Raphael Hertzog
