Hashtable Collisions

This module uses a denial-of-service (DoS) condition appearing in a variety of
programming languages. This vulnerability occurs when storing multiple values
in a hash table and all values have the same hash value. This can cause a web server
parsing the POST parameters issued with a request into a hash table to consume
hours of CPU with a single HTTP request.

Currently, only the hash functions for PHP and Java are implemented.
This module was tested with PHP + httpd, Tomcat, Glassfish and Geronimo.
It also generates a random payload to bypass some IDS signatures.
