Scientific Linux Security Update : thunderbird on SL4.x, SL5.x i386/x86_64

This script is Copyright (C) 2012-2013 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 processing of malformed content. An HTML mail
message containing malicious content could cause Thunderbird to crash
or, potentially, execute arbitrary code with the privileges of the
user running Thunderbird. (CVE-2012-0442)

The same-origin policy in Thunderbird treated http://example.com and
http://[example.com] as interchangeable. A malicious script could
possibly use this flaw to gain access to sensitive information (such
as a client's IP and user e-mail address, or httpOnly cookies) that
may be included in HTTP proxy error replies, generated in response to
invalid URLs using square brackets. (CVE-2011-3670)

Note: The CVE-2011-3670 issue cannot be exploited by a
specially-crafted HTML mail message as JavaScript is disabled by
default for mail messages. It could be exploited another way in
Thunderbird, for example, when viewing the full remote content of an
RSS feed.

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.
