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.

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
