tag_insight = "USN-1232-1 fixed vulnerabilities in the X.Org X server. A regression was
  found on Ubuntu 10.04 LTS that affected GLX support, and USN-1232-2 was
  released to temporarily disable the problematic security fix. This update
  includes a revised fix for CVE-2010-4818.

  crash, leading to a denial or service, or possibly execute arbitrary code
  with root privileges. This issue only affected Ubuntu 10.04 LTS and 10.10.
