Ubuntu Security Notice (C) 2005-2013 Canonical, Inc. / NASL script (C) 2006-2013 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related patches.
A local privilege escalation vulnerability has been discovered in the
pixmap allocation handling of the X server. By allocating a huge
pixmap, a local user could trigger an integer overflow that resulted
in a memory allocation that was too small for the requested pixmap.
This resulted in a buffer overflow which could eventually be exploited
to execute arbitrary code with full root privileges.
Update the affected packages.

Medium / CVSS Base Score : 5.1
