Microsoft has released security patches for some of its products, fixing critical flaws in the Internet Explorer browser, DirectX and Bluetooth wireless software for Windows. Some of the flaws these patches address can be exploited in Web-based attacks, where a criminal tricks the victim into visiting a malicious Web page, then takes advantage of the bug to install malicious software on the victim's Windows PC. The company also has released less-critical updates for its server products, fixing bugs in Active Directory the Windows Internet Name Service and the Pragmatic General Multicast protocol, used by Windows to stream media to many recipients. A seventh update, rated moderate, adds "kill bits" that disable buggy speech-recognition software and a program that manages Logitech devices.
