Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated XFree86 packages that fix several security issues are now
available for Red Hat Enterprise Linux 2.1.

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 input validation flaw was discovered in X.org's Security and Record
extensions. 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-2008-1377)

An integer overflow flaw was found in X.org's Render extension. 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-2008-2360)

An input validation flaw was discovered in X.org's MIT-SHM extension.
A client connected to the X.org server could read arbitrary server
memory. This could result in the sensitive data of other users of the
X.org server being disclosed. (CVE-2008-1379)

Users of XFree86 are advised to upgrade to these updated packages,
which contain backported patches to resolve these issues.
