Yahoo! Messenger Service 18 Remote Buffer Overflow Vulnerability

Yahoo! Messenger Service 18 Remote Buffer Overflow Vulnerability

Yahoo! Messenger is prone to a remote buffer-overflow vulnerability because it fails to properly bounds-check user-supplied data before copying it to an insufficiently sized memory buffer.

This vulnerability allows remote attackers to execute arbitrary machine code in the context of the affected application. Failed exploit attempts will likely crash the server, denying further service to legitimate users.

Yahoo! Messenger 8 with Voice is vulnerable.
