Scientific Linux Security Update : libpng on SL3.x, SL4.x, SL5.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 :

A flaw was discovered in libpng that could result in libpng trying to
free() random memory if certain, unlikely error conditions occurred.
If a carefully-crafted PNG file was loaded by an application linked
against libpng, it could cause the application to crash or,
potentially, execute arbitrary code with the privileges of the user
running the application. (CVE-2009-0040)

A flaw was discovered in the way libpng handled PNG images containing
'unknown' chunks. If an application linked against libpng attempted to
process a malformed, unknown chunk in a malicious PNG image, it could
cause the application to crash. (CVE-2008-1382)

All running applications using libpng or libpng10 must be restarted
for the update to take effect.
