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.
