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

This script is Copyright (C) 2012-2014 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.
