(RHSA-2006:0634) 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 are designed upon.

An integer overflow flaw in the way the X.org server processes PCF files
was discovered. A malicious authorized client could exploit this issue to
cause a denial of service (crash) or potentially execute arbitrary code
with root privileges on the X.org server. (CVE-2006-3467)

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