Yahoo Messenger
 

am not going to post the whole thing.
But you should, if you use yahoo messenger go get
an up-date.

Description

Yahoo! Messenger is a widely used program for communicating with other users over the Internet. On May 27, 2002, a buffer overflow and a URL validation vulnerability were discovered in the Yahoo! Messenger client for Microsoft Windows. Details of each vulnerability follow:

VU#137115 - Yahoo! Messenger contains a buffer overflow in the URI handler

The buffer overflow occurs during the processing of the Yahoo! Messenger URI handler (ymsgr:). This URI handler is installed at the system level for applications that use the underlying operating system when processesing URIs (such as Microsoft Internet Explorer,
Netscape Navigator 6, Microsoft Outlook, or the command shell). A URI can be sent by another Yahoo! Messenger user in a message, embedded in a web site, or sent in an HTML-renderable email message.

Yahoo! encourages users to upgrade to the latest version whenever prompted by the AutoUpdater or regularly check for updated versions of the client at
http://messenger.yahoo.com.
