CentOS 3 / 4 / 5 : libpng (CESA-2007:0356)

Medium Nessus Plugin ID 25256

Synopsis

The remote CentOS host is missing one or more security updates.

Description

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.

A flaw was found in the handling of malformed images in libpng. 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-2007-2445)

A flaw was found in the sPLT chunk handling code in libpng. 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 opened. (CVE-2006-5793)

Users of libpng should update to these updated packages which contain backported patches to correct these issues.

Red Hat would like to thank Glenn Randers-Pehrson, Mats Palmgren, and Tavis Ormandy for supplying details and patches for these issues.

Solution

Update the affected libpng packages.
