Possible security exploit in Excel

Lord Agni writes: "Microsoft is investigating new public reports of a vulnerability in Microsoft Office Excel 2003 Service Pack 2, Microsoft Office Excel Viewer 2003, Microsoft Office Excel 2002, Microsoft Office Excel 2000, and Microsoft Excel 2004 for Mac."

But don't worry:

"Additionally, as the issue has not been publicly disclosed broadly, we believe the risk at this time to be limited."
