Mozilla Ups Firefox Bug Threat, Slates Fix for Feb. 5

Mozilla Corp. bumped up the threat ranking for an unpatched Firefox bug to "high" Tuesday, but promised a fix is coming in Version 2.0.0.12, now slated for release on Feb. 5. The company's head of security, Window Snyder, confirmed that the browser, when running any of more than 600 add-ons, can be exploited to steal "session information, including session cookies and session history."

Snyder's acknowledgment followed an update by Gerry Eisenhaur, the researcher who first reported the Firefox problem. "There seems to be some confusion about what exactly the severity of this vulnerability is," Eisenhaur said on his hiredhacker.com blog. "This is not a chrome privilege escalation, but it [is] worse than just leaking some variables. I created another demo to read the sessionstore.js file. This will display information regarding your current session, [including] windows, tabs, cookies, etc."

Whether or not this is caused when flat-file addons are included by the user, this is something they need to get fixed, pronto!

Well,this could rarely happen since a few people surpass the 600 add-on mark,but i agree with markjensen,this should be patched immediatly and this only show a bliss of light when something get more & more popular,holes and more holes get discovered when it gets mass adopted.

Not rare. It doesn't take 600 add-ins to cause the problem. They are saying 600 of the add-in out there use a flat file system, and installing any of them will make you vulnerable.

As far as your conclusion goes, you make it sound like Firefox never found and fixed bugs before. Look at their bugzilla history, they are always working on fixing issues, and have been since they started.

Here is a list of extensions that are affected.

Quote from the article "Alternately, Firefox users can install the popular NoScript extension to block exploits, regardless of which add-ons have been installed."

Yet another reason to install NoScript.
