The version of Yahoo! Messenger installed on the remote host is earlier than 11.5.0.155 and is reportedly affected by an integer overflow. The error exists in the method ‘CYImage::LoadJPG’ in the file ‘YImage.dll’.
A remote attacker could execute arbitrary code by tricking a user into accepting a crafted JPG image that triggers the overflow.
Note that the photo sharing functionality is not enabled by default.
