Description

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2006:0451 advisory.

 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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL xorg-x11 package based on the guidance in RHSA-2006:0451.
