"Updated xorg-x11-server packages that fix several security issues are
now available for Red Hat Enterprise Linux 5.

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 basic low-level functionality that full-fledged graphical
user interfaces are designed upon.

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)

Multiple integer overflow flaws were found in X.org's Render
extension. A malicious authorized client could exploit these issues to
cause a denial of service (crash) or, potentially, execute arbitrary
code with root privileges on the X.Org server. (CVE-2008-2360,
CVE-2008-2361, CVE-2008-2362)

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 xorg-x11-server should upgrade to these updated packages,
which contain backported patches to resolve these issues."
