RedHat Update for libpng RHSA-2012:0317-01

Solution
Please Install the Updated Packages.
Insight
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 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.
Affected
libpng on Red Hat Enterprise Linux (v. 5 server), Red Hat Enterprise Linux AS version 4, Red Hat Enterprise Linux ES version 4, Red Hat Enterprise Linux WS version 4
