Microsoft Office Excel 2000 SP3, 2002 SP3, and 2003 SP2 and SP3; Office Excel Viewer 2003; and Office 2004 and 2008 for Mac do not properly validate index values for AxesSet records when loading Excel files, which allows remote attackers to execute arbitrary code via a crafted Excel file, aka the "Excel Indexing Validation Vulnerability."
