  script_tag(name:"insight", value:"The libpng packages contain a library of functions for creating and
  manipulating PNG (Portable Network Graphics) image format files.

  A heap-based buffer overflow flaw was found in the way libpng processed
  tEXt chunks in PNG image files. An attacker could create a
  specially-crafted PNG image file 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-2011-3048)

  Users of libpng should upgrade to these updated packages, which correct
  this issue. For Red Hat Enterprise Linux 5, they contain a backported
  patch. For Red Hat Enterprise Linux 6, they upgrade libpng to version
  1.2.49. All running applications using libpng must be restarted for the
  update to take effect.");
