3. Description:

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

A memory corruption flaw was found in the way applications, using the
libpng library and its progressive reading method, decoded certain PNG
images. An attacker could create a specially-crafted PNG image that, when
opened, could cause an application using libpng to crash or, potentially,
execute arbitrary code with the privileges of the user running the
application. (CVE-2010-1205)

A denial of service flaw was found in the way applications using the libpng
library decoded PNG images that have certain, highly compressed ancillary
chunks. An attacker could create a specially-crafted PNG image that could
cause an application using libpng to consume excessive amounts of memory
and CPU time, and possibly crash. (CVE-2010-0205)

A memory leak flaw was found in the way applications using the libpng
library decoded PNG images that use the Physical Scale (sCAL) extension. An
attacker could create a specially-crafted PNG image that could cause an
application using libpng to exhaust all available memory and possibly crash
or exit. (CVE-2010-2249)

A sensitive information disclosure flaw was found in the way applications
using the libpng library processed 1-bit interlaced PNG images. An attacker
could create a specially-crafted PNG image that could cause an application
using libpng to disclose uninitialized memory. (CVE-2009-2042)

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.

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

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

504782 - CVE-2009-2042 libpng: Interlaced Images Information Disclosure Vulnerability
566234 - CVE-2010-0205 libpng: excessive memory consumption due to highly compressed huge ancillary chunk
608238 - CVE-2010-1205 libpng: out-of-bounds memory write
