Microsoft Excel 2002 SP3, 2003 SP3, 2007 SP2, and 2010; Office 2004, 2008, and 2011 for Mac; Open XML File Format Converter for Mac; Excel Viewer SP2; and Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats SP2 do not properly validate record information during parsing of Excel spreadsheets, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted spreadsheet, aka "Excel Improper Record Parsing Vulnerability."

Security readout for executives and security teams

This is an old Microsoft Excel file-parsing flaw. A malicious spreadsheet could trigger memory corruption in affected Excel, Office for Mac, Excel Viewer, converters, or compatibility components, potentially allowing code execution or a crash. The bundle does not show active exploitation or CVSS data. Exposure is most likely where the listed legacy Microsoft Office, Excel Viewer, Mac converter, or Office Compatibility Pack components remain installed and process spreadsheets from email, web downloads, shared drives, or partners. Treat this as high priority only if affected legacy Microsoft Office components still exist. The business risk is document-borne code execution, but urgency depends on whether those old products remain in use. Mitigation focus: Review Microsoft MS11-045 and apply the vendor-recommended security update path.; Inventory and remove affected Office, Viewer, converter, and Compatibility Pack versions where no longer needed.; Restrict untrusted spreadsheet handling on systems that still require listed legacy components..
