Description A remote code execution issue exists due to improper validation of record information during the parsing of Excel spreadsheets, allowing remote attackers to execute arbitrary code or cause a denial of service via a crafted spreadsheet. This could enable an attacker to take complete control of an affected system, install programs, view, change, or delete data, or create new accounts with full user rights.

Recommendations For Microsoft Excel versions 2002 SP3, 2003 SP3, 2007 SP2, and 2010, update to a newer version to mitigate the risk. For Office for Mac versions 2004, 2008, and 2011, update to a newer version to mitigate the risk. For Open XML File Format Converter for Mac, update to a newer version to mitigate the risk. For Excel Viewer version SP2, update to a newer version to mitigate the risk. For Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats version SP2, update to a newer version to mitigate the risk. As a temporary workaround, consider avoiding the use of specially crafted Excel files until a patch is available.
