					This module exploits a memory corruption vulnerability in the Internet Explorer
				Tabular Data ActiveX Control. Microsoft reports that version 5.01 and 6 of Internet 
				Explorer are vulnerable.

				By specifying a long value as the "DataURL" parameter to this control, it is possible
				to write a NUL byte outside the bounds of an array. By targeting control flow data
				on the stack, an attacker can execute arbitrary code.
