"Updated X.org packages that correct a flaw in X.Org's composite
extension are now available for Red Hat Enterprise Linux 4.

This update has been rated as having moderate 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 are designed upon.

A flaw was found in the way X.Org's composite extension handles 32 bit
color depth windows while running in 16 bit color depth mode. If an
X.org server has enabled the composite extension, it may be possible
for a malicious authorized client to cause a denial of service (crash)
or potentially execute arbitrary code with the privileges of the X.org
server. (CVE-2007-4730)

Please note this flaw can only be triggered when using a compositing
window manager. Red Hat Enterprise Linux 4 does not ship with a
compositing window manager.

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