  A heap-based buffer overflow flaw was found in the way libxml2 decoded
  entity references with long names. A remote attacker could provide a
  specially-crafted XML file that, when opened in an application linked
  against libxml2, would cause the application to crash or, potentially,
  execute arbitrary code with the privileges of the user running the
  application. (CVE-2011-3919)
  
  An out-of-bounds memory read flaw was found in libxml2. A remote attacker

  (CVE-2011-3905)

  which contain backported patches to correct these issues. The desktop must
