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

This script is Copyright (C) 2012 Tenable Network Security, Inc.


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.
