MS08-023: Same bug, four different security bulletin ratings
Security bulletin MS08-023 addressed two ActiveX control vulnerabilities, one in a Visual Studio ActiveX control and another in a Yahoo!’s Music Jukebox ActiveX control. The security update sets the killbit for both controls. For more about how the killbit works, see the excellent three-part series (1, 2, 3) from early February in this blog.
