Title:RedHat Update for libpng RHSA-2012:0407-01
Summary:The remote host is missing an update for the 'libpng'; package(s) announced via the referenced advisory.
The remote host is missing an update for the 'libpng'
package(s) announced via the referenced advisory.

Vulnerability 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 the way libpng processed
compressed 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-2011-3045)

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
1.2.48. All running applications using libpng must be restarted for the
update to take effect.

Affected Software/OS:
libpng on Red Hat Enterprise Linux (v. 5 server)

Please Install the Updated Packages.
