Yahoo! Messenger Webcam Upload ActiveX control buffer overflow
|yahoo-webcam-upload-bo (34758)||High Risk|
The Yahoo! Messenger Webcam Upload ActiveX control (ywcupl.dll) is vulnerable to a stack-based buffer overflow. By persuading a victim to visit a specially-crafted Web page that passes an overly long "Server" property to the Send() method, a remote attacker could overflow a buffer and execute arbitrary code on the system with the privileges of the user or cause the victim's browser to crash.
Upgrade to the latest version of Yahoo! Messenger (18.104.22.1681 or later), available from the Yahoo! Messenger Web site. See References.
