Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

Multiple flaws were found in the RENDER, RECORD, and Security
extensions of X.org which did not correctly validate function
arguments. An authenticated attacker could send specially crafted
requests and gain root privileges or crash X. (CVE-2008-1377,
