  A heap-based buffer overflow flaw was found in libpng. An attacker could
  create a specially-crafted PNG image that, when opened, could cause an
  application using libpng to crash or, possibly, execute arbitrary code with
  the privileges of the user running the application. (CVE-2011-3026)

  Users of libpng and libpng10 should upgrade to these updated packages,
  which contain a backported patch to correct this issue. All running
  applications using libpng or libpng10 must be restarted for the update to
  take effect.");
