TITLE:
Mozilla Firefox 2 Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA33184

VERIFY ADVISORY:
http://secunia.com/advisories/33184/

CRITICAL:
Highly critical

IMPACT:
Security Bypass, Cross Site Scripting, Exposure of sensitive information, System access

WHERE:
From remote

SOFTWARE:
Mozilla Firefox 2.0.x
http://secunia.com/advisories/product/12434/

DESCRIPTION:
Some vulnerabilities have been reported in Mozilla Firefox, which can be exploited by malicious people to bypass certain security restrictions, disclose sensitive information, conduct cross-site scripting attacks, or potentially compromise a user's system.

1) Multiple errors in the layout engine can be exploited to corrupt memory and potentially execute arbitrary code.

2) An error in the processing of XBL bindings can be exploited to bypass the same-origin policy and read data from a target document in another domain.

Successful exploitation of this vulnerability requires that the target document contains a "" element and that the "id" of the read binding is known.

3) An error in the feed preview functionality can be exploited to execute arbitrary JavaScript code with chrome privileges.

This is related to vulnerability #3 in:
SA31984

4) An error exists when processing "XMLHttpRequest" requests to a web server which redirects the browser via a 302 HTTP status code. This can be exploited to bypass the same-origin policy and disclose sensitive information from another domain.

5) An error exists when processing JavaScript URLs redirecting the browser to another domain returning non-JavaScript data. This can be exploited to disclose sensitive information from the other domain via a "window.onerror" event handler.

6) An error when processing URLs starting with whitespace or certain control characters can be exploited to output a malformed URL when rendering a hyperlink.

7) An error in the CSS parser when processing "\0" sequences can be exploited to potentially bypass third party script sanitation routines.

8) An error when processing an XBL binding attached to an unloaded document can be exploited to bypass the same-origin policy and execute arbitrary JavaScript code in a different domain.

9) Two errors can be exploited to pollute "XPCNativeWrappers" and execute arbitrary JavaScript code with chrome privileges.

10) Several errors in the session restore feature can be exploited to execute arbitrary JavaScript code in a different domain or with chrome privileges.

The vulnerabilities are reported in versions prior to 2.0.0.19.

SOLUTION:
Update to version 2.0.0.19.

Oops! Mozilla forgets Firefox 2 patch, must re-issue update (computerworld.com)

They SWEAR this will be the last 2.0.0.x. You should be running FF3 anyway.

Just remember, every time you post one of these advisories brings to mind all the other times you DIDN'T post when there was an update. My Firefox went ahead and updated itself on its own before I read any of this stuff anyway.

With the recent windows IE issue, the fix was to use a different browser. In the past, we've pushed people to use FF via a banner add and openly supporting it. I thought that this highly critical was important enough to mention it.

I guess I can stop posting these if its such an issue.

Well, when I said "direction"; I mostly meant the UI changes with Vista and 7. I havn't had hands-on experience with 7 yet I admit.
