The Yahoo! Messenger AudioConf ActiveX control contains a buffer overflow, which could allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
Yahoo! Messenger is an instant messaging application. Yahoo! Messenger includes several ActiveX controls. The AudioConf ActiveX control, which is provided by yacscom.dll, contains a buffer overflow 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.
