Microsoft Office Excel 2000 SP3, 2002 SP3, 2003 SP2 and SP3, and 2007 Gold and SP1; Office Excel Viewer 2003 Gold and SP3; Office Excel Viewer; Office Compatibility Pack 2007 Gold and SP1; Office SharePoint Server 2007 Gold and SP1; and Office 2004 and 2008 for Mac do not properly parse Country record values when loading Excel files, which allows remote attackers to execute arbitrary code via a crafted Excel file, aka the "Excel Record Parsing Vulnerability."
