Does anyone have more information on this issue?Yes. SecuriTeam is currently assisting a researcher with reporting
this issue to Yahoo! security. Yahoo! security responded in record time, as they often do, and are working to resolve this potential security vulnerability. An official report with full credit to the researcher who discovered it will be released when the incident has been resolved. A similar vulnerability was reported on the mailing lists a few months ago, which has not been fixed. SecuriTeam assisted the researcher and Yahoo! responded and fixed the issue in a matter of a day. Yahoo! are very capable with security vulnerabilities in their software. Thanks, Gadi.----snip---- http://www.securityfocus.com/bid/20625/discuss Yahoo! Messenger is prone to a remote buffer-overflowvulnerabilitybecause it fails to properly bounds-check user-supplied databeforecopying it to an insufficiently sized memory buffer. This vulnerability allows remote attackers to execute arbitrarymachinecode in the context of the affected application. Failed exploitattemptswill likely crash the server, denying further service tolegitimateusers. Yahoo! Messenger 8 with Voice is vulnerable. ----snip---- I could not find this vulnerability reported on any other placethanbugtraq (say Secunia, iDefense, ISC).

So how fast is this "record time?" As fast as Hitler's Blitzkrieg tactics?
