  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
  could provide a specially-crafted XML file that, when opened in an
  application linked against libxml2, would cause the application to crash.
  (CVE-2011-3905)

  All users of libxml2 are advised to upgrade to these updated packages,
  which contain backported patches to correct these issues. The desktop must
  be restarted (log out, then log back in) for this update to take effect.");
