[Monique Yeaton]

---------------------

This notice is being sent in response to Technical Cyber Security  
Alert TA06-354A, December 20, 2006

Mozilla has released new versions of Firefox, Thunderbird, and  
SeaMonkey to address several vulnerabilities. Upgrades Mozilla  
Firefox 1.5.0.9, Mozilla Firefox 2.0.0.1, Mozilla Thunderbird  
1.5.0.9, and SeaMonkey 1.0.7 address these vulnerabilities. All three  
browsers automatically check for updates by default.

According to September 2006 statistics, 45% of certificates at MIT  
were obtained using Firefox/Mozilla browsers. If you are using any of  
these browsers, we advise to upgrade now.

Firefox 1.5.0.9
<http://www.mozilla.com/en-US/firefox/releases/1.5.0.9.html>

Firefox 2.0.0.1
<http://www.mozilla.com/en-US/firefox/>

Thunderbird 1.5.0.9
<http://www.mozilla.com/en-US/thunderbird/releases/1.5.0.9.html>

SeaMonkey 1.0.7
<http://www.mozilla.org/projects/seamonkey/>

The vulnerabilities found could allow a remote attacker to execute  
arbitrary code that could possibly affect the application. It could  
also allow impersonation of a seemingly secure site and cause a  
denial-of-service (DoS), making a Web page unavailable to its  
intended users.

According to Mozilla, Firefox 1.5.0.x will be maintained with  
security and stability updates until April 24, 2007. All users are  
strongly encouraged to upgrade to Firefox 2 <http://www.mozilla.com/ 
en-US/firefox/>.
