Scientific Linux Security Update : libpng on SL4.x, 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 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.
