tag_insight = "Tavis Ormandy discovered a heap overflow flaw during video-to-video
  copy operations in the Cirrus VGA extension code that is used in Xen.
  A malicious local administrator of a guest domain could potentially
  trigger this flaw and execute arbitrary code outside of the domain
  (CVE-2007-1320).

  Tavis Ormandy also discovered insufficient input validation leading to
  a heap overflow in the NE2000 network driver in Xen.  If the driver
  is in use, a malicious local administrator of a guest domain could
  potentially trigger this flaw and execute arbitrary code outside of
  the domain (CVE-2007-1321, CVE-2007-5729, CVE-2007-5730).
  
  Steve Kemp found that xen-utils used insecure temporary files within
  the xenmon tool that could allow local users to truncate arbitrary
  files (CVE-2007-3919).
  
  Joris van Rantwijk discovered a flaw in Pygrub, which is used as a
  boot loader for guest domains.  A malicious local administrator of
  a guest domain could create a carefully-crafted grub.conf file which
  could trigger the execution of arbitrary code outside of that domain
  (CVE-2007-4993).
  
  Updated packages have been patched to prevent these issues.";
