Microsoft's Patch Day bundle this month will be a whopper: 12 bulletins with fixes for a wide range of serious security vulnerabilities.
Five of the 12 bulletins will cover remotely exploitable bugs in the Windows operating system while three will deal with Microsoft Office flaws. While there is a strong likelihood that the Office patches will address the known flaws that have already been used in zero-day attacks, it's also a safe guess that some of the Word and Excel issues will remain unpatched for at least another month.
Microsoft also gave a heads-up to users of its security suites -- Windows Live OneCare, Microsoft Antigen, Windows Defender and Microsoft Forefront -- that patches are coming down the pike for a flaw (or flaws) rated critical.
The Patch Tuesday updates will also provide cover for separate issues affecting both Windows Update and Visual Studio; an "important" bug in Step-by-Step Interactive Training; and a critical vulnerability in MDAC (Microsoft Data Access Components)
