3. Description:

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.

Multiple input sanitization flaws were found in the X.Org GLX (OpenGL
extension to the X Window System) extension. A malicious, authorized client
could use these flaws to crash the X.Org server or, potentially, execute
arbitrary code with root privileges. (CVE-2010-4818)

An input sanitization flaw was found in the X.Org Render extension. A
malicious, authorized client could use this flaw to leak arbitrary memory
from the X.Org server process, or possibly crash the X.Org server.
(CVE-2010-4819)

Users of xorg-x11-server should upgrade to these updated packages, which
contain backported patches to resolve these issues. All running X.Org
server instances must be restarted for this update to take effect.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
