Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having moderate
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

3. Description:

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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258

5. Bugs fixed (http://bugzilla.redhat.com/):
