The Yahoo! Webcam image upload ActiveX control contains a stack buffer overflow, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
Yahoo! Webcam is a component of Yahoo! Messenger that allows users to chat via webcams over a network. Yahoo! Webcam Upload includes an ActiveX control provided by the file ywcupl.dll . This ActiveX control contains a stack buffer overflow vulnerability in the Server property.
We are aware of publicly available exploit code for this vulnerability.
By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary code with the privileges of the user. The attacker could also cause Internet Explorer (or the program using the WebBrowser control) to crash.
