Updated libpng packages that fix security issues are now available for Red Hat Enterprise Linux.
This update has been rated as having moderate security impact by the Red Hat Security Response Team.
The libpng package contains a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files.
Several flaws were discovered in the way libpng handled various PNG image chunks. An attacker could create a carefully crafted PNG image file in such a way that it could cause an application linked with libpng to crash when the file was manipulated. (CVE-2007-5269)
Users should update to these updated packages which contain a backported patch to correct these issues.
