Scientific Linux Security Update : libpng on SL5.x, SL6.x i386/x86_64 (20120320)

medium Nessus Plugin ID 61286

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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 the way libpng processed compressed chunks in PNG image files. An attacker could create a specially crafted PNG image file 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-2011-3045)

Users of libpng should upgrade to these updated packages, which correct this issue. For Scientific Linux 5, they contain a backported patch. For Scientific Linux 6, they upgrade libpng to version 1.2.48.
All running applications using libpng must be restarted for the update to take effect.

Solution

Update the affected packages.
