Security readout for executives and security teams

This is an old Microsoft Excel vulnerability where opening a malicious spreadsheet could let an attacker run code or crash Excel. Business risk is mainly from legacy Office, Excel Viewer, Mac Office, or compatibility pack installations that still process untrusted spreadsheets. Exposure is most likely in environments retaining Excel 2002 SP3, 2003 SP3, 2007 SP2, Office 2004/2008 for Mac, Excel Viewer SP2, Open XML Converter for Mac, or the Office Compatibility Pack SP2. Prioritize remediation where legacy Office still opens external spreadsheets, especially on user workstations. If affected products are retired, document the non-exposure and monitor for forgotten legacy systems. Mitigation focus: Review Microsoft MS11-045 guidance and apply the relevant security update.; Remove or isolate unsupported legacy Office and Excel Viewer installations.; Restrict handling of untrusted Excel files on vulnerable systems..
