  An uninitialized memory read issue was found in the way libpng processed
  certain PNG images that use the Physical Scale (sCAL) extension. An
  attacker could create a specially-crafted PNG image that, when opened,
  could cause an application using libpng to crash. (CVE-2011-2692)

  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.");
