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

A memory corruption flaw was found in the way applications, using the
libpng library and its progressive reading method, decoded certain PNG
images. An attacker could create a specially crafted PNG image that,
when opened, could cause an application using libpng to crash or,
potentially, execute arbitrary code with the privileges of the user
running the application. (CVE-2010-1205)

A denial of service flaw was found in the way applications using the
libpng library decoded PNG images that have certain, highly compressed
ancillary chunks. An attacker could create a specially crafted PNG
image that could cause an application using libpng to consume
excessive amounts of memory and CPU time, and possibly crash.
(CVE-2010-0205)

A memory leak flaw was found in the way applications using the libpng
library decoded PNG images that use the Physical Scale (sCAL)
extension. An attacker could create a specially crafted PNG image that
could cause an application using libpng to exhaust all available
memory and possibly crash or exit. (CVE-2010-2249)

A sensitive information disclosure flaw was found in the way
applications using the libpng library processed 1-bit interlaced PNG
images. An attacker could create a specially crafted PNG image that
could cause an application using libpng to disclose uninitialized
memory. (CVE-2009-2042)

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