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.
