4) Description of Vulnerability
Secunia Research has discovered a vulnerability in Firefox, which can
be exploited by malicious people to potentially compromise a user's
system.
The vulnerability is caused due to a race condition when accessing the
private data of an NPObject JS wrapper class object if navigating away
