tag_insight = "The libxml2 library is a development toolbox providing the implementation
  of various XML standards.

  It was found that the hashing routine used by libxml2 arrays was
  susceptible to predictable hash collisions. Sending a specially-crafted
  message to an XML service could result in longer processing time, which
  could lead to a denial of service. To mitigate this issue, randomization
  has been added to the hashing function to reduce the chance of an attacker
  successfully causing intentional collisions. (CVE-2012-0841)
  
  All users of libxml2 are advised to upgrade to these updated packages,
  which contain a backported patch to correct this issue. The desktop must
  be restarted (log out, then log back in) for this update to take effect.";
