Yahoo! Messenger fails to properly handle webcam streams, which may allow a remote attacker to execute arbitrary code.
Yahoo! Messenger is an instant messaging application that is available for Windows, Mac, Unix, web, and mobile systems. Some version of Yahoo! Messenger, such as the Windows and Mac versions, support webcam use. When Yahoo! Messenger views a webcam stream, it makes a connection to port 5100/tcp. The webcam video stream is sent as a JPEG 2000 code stream. Yahoo! Messenger appears to require user interaction to connect a webcam stream.
Yahoo! Messenger contains a heap overflow in the handling of a malformed JPEG 2000 code streams. Exploit code that causes a denial of service is publicly available.
A remote attacker may be able to execute arbitrary code with the privileges of the user running Yahoo! Messenger. This vulnerability may also cause a denial of service by causing Yahoo! Messenger to crash.
