Microsoft Corp. patched the first critical vulnerability in Windows 7 Tuesday as it rolled out an update that fixes three flaws in the new operating system's kernel.
The MS09-006 update, which researchers tagged as the most serious of the three issued Tuesday and the one to patch first, includes a critical bug in the kernel's processing of input delivered by the graphical device interface (GDI), the core graphics rendering component of Windows.
According to Microsoft, the public beta of Windows 7, as well as previews of other editions of the OS, contain the three flaws fixed by MS09-006. "These vulnerabilities were reported after the release of Windows Server 2008 Service Pack 2 Beta, Windows Vista Service Pack 2 Beta, and Windows 7 Beta,"
