included with Yahoo! Messenger.
The version of this ActiveX control on the remote host has a buffer
overflow triggered by calling the control's 'createAndJoinConference'
method with large values for the 'socksHostname' and 'hostname'
properties. If an attacker can trick a user on the affected host into
visiting a specially crafted web page, this issue could be leveraged
to execute arbitrary code on the host subject to the user's
privileges.");
