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

This script is Copyright (C) 2012-2013 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing a security update.

Description :

Several flaws were found in the processing of malformed content.
Malicious content could cause Thunderbird to crash or, potentially,
execute arbitrary code with the privileges of the user running
Thunderbird. (CVE-2012-4214, CVE-2012-4215, CVE-2012-4216,
CVE-2012-5829, CVE-2012-5830, CVE-2012-5833, CVE-2012-5835,
CVE-2012-5839, CVE-2012-5840, CVE-2012-5842)

A buffer overflow flaw was found in the way Thunderbird handled GIF
(Graphics Interchange Format) images. Content containing a malicious
GIF image could cause Thunderbird to crash or, possibly, execute
arbitrary code with the privileges of the user running Thunderbird.
(CVE-2012-4202)

A flaw was found in the way Thunderbird decoded the HZ-GB-2312
character encoding. Malicious content could cause Thunderbird to run
JavaScript code with the permissions of different content.
(CVE-2012-4207)

A flaw was found in the location object implementation in Thunderbird.
Malicious content could possibly use this flaw to allow restricted
content to be loaded by plug-ins. (CVE-2012-4209)

A flaw was found in the way cross-origin wrappers were implemented.
Malicious content could use this flaw to perform cross-site scripting
attacks. (CVE-2012-5841)

A flaw was found in the evalInSandbox implementation in Thunderbird.
Malicious content could use this flaw to perform cross-site scripting
attacks. (CVE-2012-4201)

Note: All issues except CVE-2012-4202 cannot be exploited by a
specially-crafted HTML mail message as JavaScript is disabled by
default for mail messages. They could be exploited another way in
Thunderbird, for example, when viewing the full remote content of an
RSS feed.

After installing the update, Thunderbird must be restarted for the
changes to take effect.
