Debian alert: New gnome-gv packages fix buffer overflow
Zen-parse discovered a buffer overflow in gv, a PostScript and PDF
viewer for X11. The same code is present in gnome-gv. This problem
is triggered by scanning the PostScript file and can be exploited by
an attacker sending a malformed PostScript or PDF file. The attacker
is able to cause arbitrary code to be run with the privileges of the
victim.
