This signature detects an attempt to exploit an ActiveX control buffer overflow vulnerability in Dell Webcam Center.
Dell Webcam Center is an application for the Dell laptop integrated webcam.
The application is prone to multiple stack-based buffer-overflow vulnerabilities that affect the 'BackImage', 'ScriptName', 'ModelName', and 'SRC' properties. Specifically, these issues are triggered by calling the 'sprintf()' function when the 'crazytalk4.ocx' ActiveX control loads the 'CrazyTalk4Native.dll' library.
Attackers may exploit these issues to execute arbitrary code in the context of the application using the ActiveX control (typically Internet Explorer). Failed exploit attempts will likely result in denial-of-service conditions.
