Details

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)

attacker could exploit this to read arbitrary memory locations within X,
exposing sensitive information. (CVE-2008-1379)
