Mozilla Updates for Multiple Vulnerabilities

 

Original release date: March 27, 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 and the Vulnerability Notes Database.

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 2.0.0.13,

Thunderbird 2.0.0.13, and SeaMonkey 1.1.9.

 

Disable JavaScript

 

Some of these vulnerabilities can be mitigated by disabling JavaScript

or by using the NoScript extension. For more information about

configuring Firefox, please see the Securing Your Web Browser

document. Thunderbird disables JavaScript by default.
