This signature detects attempts to use unsafe ActiveX controls in Yahoo Messenger YMailAttach. An attacker can create a malicious Web site containing Web pages with dangerous ActiveX controls, which if accessed by a victim, allows the attacker to gain control of the victim's client browser.
The YMailAttach ActiveX control shipped with Yahoo! Messenger is prone to a buffer-overflow vulnerability. The software fails to perform sufficient bounds-checking of user-supplied input before copying it to an insufficiently sized memory buffer. Yahoo! Messenger versions released prior to November 2, 2006 are vulnerable to this issue.
