Microsoft Excel 2002 SP3 and 2003 SP3, Office 2004 and 2008 for Mac, and Open XML File Format Converter for Mac 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 Out of Bounds WriteAV Vulnerability."

Security readout for executives and security teams

This is an old Microsoft Excel file-parsing flaw. A malicious spreadsheet could trigger memory corruption, allowing code execution or a crash when opened in affected legacy Office products. Exposure is mainly in organizations still running the listed legacy Microsoft Office products or converters, especially where users can receive and open spreadsheets from email, web downloads, or shared storage. Treat as high priority if legacy Office remains in production. The business risk is user-driven compromise from malicious spreadsheets, with no active exploitation evidence in the provided sources. Mitigation focus: Apply Microsoft guidance from MS11-045 where affected products remain in use.; Retire or isolate unsupported legacy Office and converter installations.; Restrict opening spreadsheets from untrusted sources on legacy systems..
