Scientific Linux Security Update : thunderbird on 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 :

Mozilla Thunderbird is a standalone mail and newsgroup client.

A flaw was found in the way Thunderbird handled frame objects with
certain names. An attacker could use this flaw to cause a plug-in to
grant its content access to another site or the local file system,
violating the same-origin policy. (CVE-2011-2999)

An integer underflow flaw was found in the way Thunderbird handled
large JavaScript regular expressions. An HTML mail message containing
malicious JavaScript could cause Thunderbird to access already freed
memory, causing Thunderbird to crash or, potentially, execute
arbitrary code with the privileges of the user running Thunderbird.
(CVE-2011-2998)

All Thunderbird users should upgrade to this updated package, which
resolves these issues. All running instances of Thunderbird must be
restarted for the update to take effect.
