"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,
CVE-2008-2360, CVE-2008-2361, CVE-2008-2362)

It was discovered that the MIT-SHM extension of X.org did not
correctly validate the location of memory during an image copy. An
authenticated attacker could exploit this to read arbitrary memory
locations within X, exposing sensitive information. (CVE-2008-1379).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
