Microsoft Excel 2002 SP3, 2003 SP3, 2007 SP2, and 2010; Office 2004, 2008, and 2011 for Mac; Open XML File Format Converter for Mac; and Excel Viewer SP2 do not properly handle errors during the parsing of Office Art records in Excel spreadsheets, which allows remote attackers to execute arbitrary code via a malformed object record, related to a "stray reference," aka "Excel Linked List Corruption Vulnerability."

Security readout for executives and security teams

This is an old Microsoft Excel remote code execution issue. A specially malformed spreadsheet can corrupt Excel’s internal handling of drawing objects and potentially run attacker-controlled code when opened. Business risk exists mainly where legacy Office, Excel Viewer, or Mac converter components remain installed. Exposure is most likely on endpoints still running the listed 2002, 2003, 2007, 2010, Mac Office, Excel Viewer SP2, or Mac converter versions. Modern environments are exposed only if these legacy components remain present or unpatched. Treat as a high-priority legacy exposure review. The issue enables code execution through a document-opening workflow, but urgency depends on whether affected Microsoft Office versions still exist in the environment. Mitigation focus: Apply Microsoft MS11-021 guidance and updates where applicable.; Inventory and remove unsupported legacy Excel, Viewer, and converter components.; Restrict opening untrusted Excel spreadsheets from email or web sources..
