Heap-based buffer overflow in Microsoft Excel 2007 SP2 and SP3 and 2010 Gold and SP1, Excel Viewer, and Office Compatibility Pack SP2 and SP3 allows remote attackers to execute arbitrary code via a crafted spreadsheet that triggers incorrect handling of memory during opening, aka "Excel MergeCells Record Heap Overflow Vulnerability."

Security readout for executives and security teams

This flaw affects older Microsoft Excel components. A malicious spreadsheet could corrupt memory when opened and potentially let an attacker run code as the user. Business urgency is mainly for organizations that still have legacy Excel, Excel Viewer, or Office Compatibility Pack installations. Exposure is likely limited to endpoints or servers that still have the affected legacy Microsoft Office components installed and can open untrusted spreadsheets from email, web downloads, file shares, or archives. Treat as high priority only where legacy Office components remain. Modern supported Office estates are less likely to be affected, but unpatched legacy document-handling systems create credible code-execution risk from routine business files. Mitigation focus: Apply Microsoft guidance and security updates from MS12-030 where applicable.; Remove or replace unsupported legacy Excel, Excel Viewer, and Office Compatibility Pack installations.; Prioritize systems that receive or process untrusted spreadsheet files..
