Details

USN-1620-1 fixed vulnerabilities in Firefox. This update provides the
corresponding updates for Thunderbird. Please note that Thunderbird is only
affected by window.location issues through RSS feeds and extensions that
load web content.

Original advisory details:

Mariusz Mlynski and others discovered several flaws in Firefox that allowed
a remote attacker to conduct cross-site scripting (XSS) attacks.
(CVE-2012-4194, CVE-2012-4195)

Antoine Delignat-Lavaud discovered a flaw in the way Firefox handled the
Location object. If a user were tricked into opening a specially crafted
page, a remote attacker could exploit this to bypass security protections
and perform cross-origin reading of the Location object. (CVE-2012-4196)

The problem can be corrected by updating your system to the following package versions:

Ubuntu 12.10
Ubuntu 12.04

After a standard system update you need to restart Thunderbird to make all
