(RHSA-2005:396) xorg-x11 security update

X.org is an open source implementation of the X Window System. It
provides the basic low-level functionality that full-fledged graphical
user interfaces (GUIs) such as GNOME and KDE are designed upon.

Several integer overflow bugs were found in the way X.org parses pixmap
images. It is possible for a user to gain elevated privileges by loading a
specially crafted pixmap image. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CAN-2005-2495 to this issue.

Users of X.org should upgrade to these updated packages, which contain a
backported patch and are not vulnerable to this issue.
