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 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.

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/kb/docs/DOC-11259

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

790737 - CVE-2011-3026 libpng: Heap-buffer-overflow in png_decompress_chunk (MFSA 2012-11)
