RHEL 3 : libpng (RHSA-2009:0340)

Medium Nessus Plugin ID 35776


The remote Red Hat host is missing one or more security updates.


Updated libpng and libpng10 packages that fix a security issue are now available for Red Hat Enterprise Linux 3.

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)

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.


Update the affected packages.
