And here is the corresponding advisory re:Firefox from http://secunia.com/advisories/37699/ :

Description:
Some [highly critical] vulnerabilities have been reported in Mozilla Firefox, which can be exploited by malicious people to conduct spoofing attacks, bypass certain security restrictions, manipulate certain data, disclose sensitive information, or compromise a user's system.

1) Multiple errors in the browser engine can be exploited to corrupt memory.

2) Multiple errors in the JavaScript engine can be exploited to corrupt memory.

3) Multiple errors in the included liboggplay library can be exploited to corrupt memory.

4) An integer overflow error in the included Theora library can be exploited to cause a heap-based buffer overflow via a specially crafted video file.

5) An error in the implementation of the NTLM authentication protocol can be exploited to reflect the user's NTLM credentials to an arbitrary application.

6) An error when handling HTTP redirections to "https://" URLs can be exploited to incorrectly display SSL indicators for an insecure page.

7) An error when handling invalid URLs can be exploited to place an arbitrary and apparently legitimate URL in the location bar.

8) An error when opening content windows from a chrome window can be exploited to execute arbitrary JavaScript code with chrome privileges via the "window.opener" property.

NOTE: This vulnerability can only be exploited via certain add-ons opening untrusted web content.

9) An error when generating "GeckoActiveXObject()" exception messages can be exploited to determine the presence of COM objects and potentially track a user across browsing sessions.

Solution:
Update to version 3.0.16 or 3.5.6.
