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)
