Mozilla Updates for Multiple Vulnerabilities

Original release date: November 14, 2008
Last revised: --
Source: US-CERT


Systems Affected

* Mozilla Firefox
* Mozilla Thunderbird
* Mozilla SeaMonkey

Other products based on Mozilla components may also be affected.


Overview

New versions of Firefox, Thunderbird, and SeaMonkey address several
vulnerabilities, the most severe of which could allow a remote
attacker to execute arbitrary code on an affected system.


I. Description

The Mozilla and the SeaMonkey projects have released new versions
of Firefox, Thunderbird and SeaMonkey to address several
vulnerabilities. Further details about these vulnerabilities are
available in Mozilla Foundation Security Advisories. An attacker
could exploit these vulnerabilities by convincing a user to view a
specially crafted HTML document, such as a web page or an HTML
email message.


II. Impact

While the impacts of the individual vulnerabilities vary, the most
severe could allow a remote, unauthenticated attacker to execute
arbitrary code on a vulnerable system. An attacker may also be able
to cause a denial of service or execute cross-site scripting
attacks.


III. Solution

Upgrade

These vulnerabilities are addressed in Mozilla Firefox 3.0.4,
Firefox 2.0.0.18, Thunderbird 2.0.0.18, and SeaMonkey 1.1.13.
