RHEL 4 / 5 : thunderbird (RHSA-2011:1438)

Medium Nessus Plugin ID 56742


The remote Red Hat host is missing a security update.


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

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

Mozilla Thunderbird is a standalone mail and newsgroup client.

A cross-site scripting (XSS) flaw was found in the way Thunderbird handled certain multibyte character sets. Malicious, remote content could cause Thunderbird to run JavaScript code with the permissions of different remote content. (CVE-2011-3648)

Note: This 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 this issue. All running instances of Thunderbird must be restarted for the update to take effect.


Update the affected thunderbird package.
