RHEL 4 / 5 : thunderbird (RHSA-2012:0085)

high Nessus Plugin ID 57788

Language:

Synopsis

The remote Red Hat host is missing a security update.

Description

An updated thunderbird package that fixes two security issues is now available for Red Hat Enterprise Linux 4 and 5.

The Red Hat Security Response Team has rated this update as having critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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.

Solution

Update the affected thunderbird package.
