The latest version of Yahoo! Messenger (Version 22.214.171.1241 ) fixes a vulnerability with the Webcam ActiveX control, commonly referred to as a buffer overflow. It was released on 8 of this month.
Yahoo! messenger has been one of my favourite instant messaging program as most of my friends are on it. I like the new improved features which includes voice capabilities and the fact that it is now integrated with MSN, so that I can also invite my friends who have only a Hotmail account.
Just to warn you, one thing I didn't like about the Yahoo! Messenger was that it adds some stuff without telling us. When you install the program, choose the custom install and choose the stuff you want to remove (or add). In my case, I deselected all.
