New Mesa patch released for Red Hat 6, resolving significant out-of-bounds vulnerabilities and possible buffer overflow risks.
Updated mesa packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6

Solution

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

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258

Summary

Mesa provides a 3D graphics API that is compatible with Open Graphics Library (OpenGL). It also provides hardware-accelerated drivers for many popular graphics chips.
An out-of-bounds access flaw was found in Mesa. If an application using Mesa exposed the Mesa API to untrusted inputs (Mozilla Firefox does this), an attacker could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2013-1872)
It was found that Mesa did not correctly validate messages from the X server. A malicious X server could cause an application using Mesa to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2013-1993)
All users of Mesa are advised to upgrade to these updated packages, which contain backported patches to correct these issues. All running applications linked against Mesa must be restarted for this update to take effect.
