Zen-parse discovered a buffer overflow in gv, a PostScript and PDF viewer for X11. The same code is present in kghostview which is part of the KDE-Graphics package. 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.
