Debian advisory: xloadimage buffer overflow

Author: JT Smith

The version of xloadimage (a graphics files viewer for X) that was
shipped in Debian GNU/Linux 2.2 has a buffer overflow in the code that
handles FACES format images. This could be exploited by an attacker by
tricking someone into viewing a specially crafted image using xloadimage
which would allow him to execute arbitrary code.
