Yahoo! Messenger Webcam Viewer YWCVWR.DLL ActiveX Control Denial of Service Vulnerability

Yahoo! Messenger Webcam Viewer YWCVWR.DLL ActiveX Control Denial of Service Vulnerability

Yahoo! Messenger Webcam Viewer Networking and Imaging ActiveX control is prone to a denial-of-service vulnerability because it fails to perform adequate checks on user-supplied data.

Successfully exploiting this issue allows remote attackers to crash applications that use the affected control (typically Internet Explorer). Remote code execution may also be possible, but has not been confirmed.

Yahoo! Messenger 8.0.1 is vulnerable; other versions may also be affected.
