This update has been rated as having important security impact by the Red

3. Description:

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.
