  A denial of service flaw was found in the way libxml2 performed string
  substitutions when entity values for entity references replacement was
  enabled. A remote attacker could provide a specially-crafted XML file that,
  when processed by an application linked against libxml2, would lead to
  excessive CPU consumption. (CVE-2013-0338)

  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.");
