  A buffer overflow flaw was found in the way libpng processed certain PNG
  image files. An attacker could create a specially-crafted PNG image that,
  when opened, could cause an application using libpng to crash or,
  potentially, execute arbitrary code with the privileges of the user running
  the application. (CVE-2011-2690)

  Note: The application behavior required to exploit CVE-2011-2690 is rarely
  used. No application shipped with Red Hat Enterprise Linux behaves this
  way, for example.

  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 should upgrade to these updated packages, which contain
  backported patches to correct these issues. All running applications using
  libpng must be restarted for the update to take effect.");
