activePDF WebGrabber version 3.8.2.0 contains a stack-based buffer overflow vulnerability in the GetStatus() method of the APWebGrb.ocx ActiveX control. By passing an overly long string to this method, a remote attacker can execute arbitrary code in the context of the vulnerable process. Although the control is not marked safe for scripting, exploitation is possible via crafted HTML content in Internet Explorer under permissive security settings.
