Barely one week after Microsoft patched several flaws in its Internet Explorer browser, a French research team has found yet another. Worse, an exploit (often a precursor to a virus, a worm, or a criminal hacker attack) already exists, so the clock is ticking. The flaw involves MSDDS.DLL, which stands for Microsoft Design Tools Diagram Surface and is part of Microsoft Visual Studio, however you don't have to have that software installed to have the .dll on your system. A variety of other products, including Microsoft Office 2000 through XP, .Net, and Visio install MSDDS.DLL. Microsoft currently does not have a patch available, so users are advised to disable ActiveX or consult this Internet Storm Center page for more workaround suggestions.
