Title:RedHat Update for libpng RHSA-2012:0317-01
Summary:The remote host is missing an update for the 'libpng'; package(s) announced via the referenced advisory.
Description:Summary:
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 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 Software/OS:
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

Solution:
Please Install the Updated Packages.
