#1. Remote denial of service in Yahoo! Messenger.

From: http://www.pandasoftware.com
Madrid, May 19, 2005 - A vulnerability has been reported in Yahoo!
Messenger that could lead to a denial of service, with remote attackers being able to disconnect users from Chat sessions.

The problem lies in the way that Yahoo! Messenger processes arguments in YMSGR: URL handler links. An attacker modifying the links with certain characters after the colon could create malformed packets to send to Yahoo! YMSG servers. When these packets are sent, Yahoo! will immediately disconnect users from the chat session.

The problem affects Yahoo! Messenger versions 5.0 and 6.0 and all details have been published along with proof of concepts with malicious urls that could disconnect a user.
