activePDF WebGrabber version 3.8.2.0 contains a stack-based buffer overflow vulnerability in the GetStatus() method of the APWebGrb.ocx ActiveX control.

Although the control is not marked safe for scripting, exploitation is possible via crafted HTML content in Internet Explorer under permissive security settings.
