"Updated X.org packages that fix a security issue are now available for
Red Hat Enterprise Linux 4.

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

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 such as GNOME and KDE are designed upon.

A buffer overflow flaw in the X.org server RENDER extension 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-2006-1526)

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

This issue does not affect Red Hat Enterprise Linux 2.1 or 3."
