Danger! Yahoo Messenger vulnerability
McAfee have been able to reproduce a vulnerability in Yahoo! Messenger version 184.108.40.2063 based on information provided in some security forums in China. All that is required to infect a system using the vulnerability is to convince a Yahoo Messenger user to accept a webcam invitation.
McAfee reports that this latest vulnerability is not the same as the Webcam vulnerability that was patched back in June.
It is recommended that:
1) NEVER webcam invitations from untrusted sources
2) Block outgoing traffic on TCP 5100
