"Updated XFree86 packages that fix a security issue are now available
for Red Hat Enterprise Linux 2.1 and 3.

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

XFree86 is an implementation of the X Window System, which provides
the core functionality for the Linux graphical desktop.

An integer overflow flaw in the way the XFree86 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 XFree86 server.
(CVE-2006-3467)

Users of XFree86 should upgrade to these updated packages, which
contain a backported patch and is not vulnerable to this issue."
