Yahoo! Messenger IMvironment buffer overflow
|yahoo-messenger-imvironment-bo (8265)||Low Risk|
Yahoo! Messenger is vulnerable to a denial of service attack, caused by a buffer overflow in the IMvironment field of the Yahoo protocol. By sending a message containing an overly large IMvironment field using a malicious Yahoo! Messenger client, a remote attacker could overflow a buffer and cause the recipient's Messenger client to crash.
