  divert data from a legitimate site to an attacker-specified site.
  Successful exploits will allow the attacker to manipulate cache data,
  potentially facilitating man-in-the-middle, site-impersonation, or denial-of-
  service attacks.

  Successfully exploiting of the Buffer Overflow vulnerability allows a
  remote attacker to execute arbitrary code with superuser privileges,
  resulting in a complete compromise of the affected computer. Failed
  exploits will cause a denial of service.");
