Critical Nessus Plugin ID 68361


The remote Oracle Linux host is missing a security update.


From Red Hat Security Advisory 2011:1343 :

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 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.

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.


Update the affected thunderbird package.
