Yahoo IM Vulnerabilities: Patched

Yahoo has patched a buffer overflow vulnerability in its instant-messaging tool that would have enabled attackers to potentially execute code on a compromised machine.

The flaw exists in an ActiveX control that is part of the Yahoo Messenger audio conference control. If exploited, a buffer overflow could cause a user to be involuntarily logged out of a chat or instant messaging session, the crash of an application such as Internet Explorer or the execution of code.
