xloadimage security update

A new xloadimage package that fixes bugs in handling malformed tiff and
pbm/pnm/ppm images, and in handling metacharacters in file names is now
available.

This update has been rated as having low security impact by the Red Hat
Security Response Team.

The xloadimage utility displays images in an X Window System window, loads
images into the root window, or writes images into a file. Xloadimage
supports many image types (including GIF, TIFF, JPEG, XPM, and XBM).

A flaw was discovered in xloadimage via which an attacker can construct a
NIFF image with a very long embedded image title. This image can cause a
buffer overflow. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2005-3178 to this issue.

All users of xloadimage should upgrade to this erratum package, which
contains backported patches to correct these issues.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied. Use Red Hat
