This module exploits a function prototype mismatch on the CQOle ActiveX
control in IBM Rational ClearQuest < 7.1.1.9, < 7.1.2.6 or < 8.0.0.2 which
allows reliable remote code execution when DEP isn't enabled.

ESP is pointing to the second argument of RegisterSchemaRepoFromFileByDbSet and no to the stored EIP on
the stack. The ret from MFC80U!_AfxDispatchCall allows to get control on a reliable way when DEP is
disabled
