RHEL 4 / 5 / 6 : libpng (RHSA-2012:0317)

high Nessus Plugin ID 58068

Language:

Synopsis

The remote Red Hat host is missing a security update for libpng.

Description

The remote Redhat Enterprise Linux 4 / 5 / 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2012:0317 advisory.

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

A heap-based buffer overflow flaw was found in libpng. An attacker could create a specially-crafted PNG image that, when opened, could cause an application using libpng to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2011-3026)

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

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL libpng package based on the guidance in RHSA-2012:0317.
