"From Red Hat Security Advisory 2009:0333 :

Updated libpng and libpng10 packages that fix a couple of security
issues are now available for Red Hat Enterprise Linux 2.1, 4, and 5.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

The libpng packages contain a library of functions for creating and
manipulating PNG (Portable Network Graphics) image format files.

A flaw was discovered in libpng that could result in libpng trying to
free() random memory if certain, unlikely error conditions occurred.
If a carefully-crafted PNG file was loaded by an application linked
against libpng, it could cause the application to crash or,
potentially, execute arbitrary code with the privileges of the user
running the application. (CVE-2009-0040)

A flaw was discovered in the way libpng handled PNG images containing
'unknown' chunks. If an application linked against libpng attempted to
process a malformed, unknown chunk in a malicious PNG image, it could
cause the application to crash. (CVE-2008-1382)

Users of libpng and libpng10 should upgrade to these updated packages,
which contain backported patches to correct these issues. All running
applications using libpng or libpng10 must be restarted for the update
to take effect."
