Mozilla Updates for Multiple Vulnerabilities

   Original release date: July 18, 2007
   Last revised: --
   Source: US-CERT


Systems Affected

     * Mozilla Firefox
     * Mozilla Thunderbird

   Other products based on Mozilla components may also be affected.


Overview

   The Mozilla web browser and derived products contain several
   vulnerabilities, the most severe of which could allow a remote
   attacker to execute arbitrary code on an affected system.


I. Description

   Mozilla has released new versions of Firefox and Thunderbird to
   address several vulnerabilities. Further details about these
   vulnerabilities are available from Mozilla 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 obtain private information.


III. Solution


Upgrade

   These vulnerabilities are addressed in Mozilla Firefox 2.0.0.5 and
   Thunderbird 2.0.0.5.


Disable JavaScript

   Some of these vulnerabilities can be mitigated by disabling JavaScript
   or using the NoScript extension. For more information about
   configuring Firefox, please see the Securing Your Web Browser
   document. Thunderbird disables JavaScript and Java by default.
