"Microsoft has issued seven patches addressing 10 vulnerabilities, including four rated 'critical' as part of this months patching cycle. The critical patches apply to its Windows operating system (OS), Internet Explorer (IE) and, unusually, a Bluetooth component.
The Bluetooth patch, MS09-030, targets a third-party ActiveX control that comes bundled with Logitech hardware, including its mice and keyboards. And it marks Microsoft's first ever patching of its Windows implementation of the Bluetooth stack."
