TITLE:
Mozilla Firefox Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA29526

VERIFY ADVISORY:
http://secunia.com/advisories/29526/

CRITICAL:
Highly critical

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

WHERE:
>From remote

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

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

1) An unspecified error in the handling of "XPCNativeWrappers" can
lead to the execution of arbitrary Javascript code with the user's
privileges via "setTimeout()" calls.

This is related to vulnerability #7 in:
SA27311

2) Various errors in the handling of Javascript code can be exploited
to conduct cross-site scripting attacks or execute arbitrary code.

3) Various errors in the layout engine can be exploited to cause a
memory corruption.

4) Various errors in the Javascript engine can be exploited to cause
a memory corruption.

Successful exploitation of these vulnerabilities may allow execution
of arbitrary code.

5) An error within the handling of HTTP "Referer:" headers sent with
requests to URLs containing "Basic Authentication" credentials having
an empty username can be exploited to bypass cross-site request
forgery protections.

6) The problem is that Firefox offers a previously configured private
SSL certificate when establishing connections to webservers requesting
SSL Client Authentication. This can potentially be exploited to
disclose sensitive information via a malicious webserver.

7) An error in the handling of the "jar:" protocol can be exploited
to establish connections to arbitrary ports on the local machine.

This is related to vulnerability #10 in:
SA29239

8) An error when displaying XUL pop-up windows can be exploited to
hide the window's borders and facilitate phishing attacks.

The vulnerabilities are reported in versions prior to 2.0.0.13.

SOLUTION:
Update to version 2.0.0.13.
