              Technical Cyber Security Alert TA08-319A


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.
