Microsoft PowerPoint 2002 SP3, 2003 SP3, 2007 SP2, and 2010; Office 2004, 2008, and 2011 for Mac; Open XML File Format Converter for Mac; Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats SP2; PowerPoint Viewer; PowerPoint Viewer 2007 SP2; and PowerPoint Web App do not properly validate PersistDirectoryEntry records in PowerPoint documents, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a Slide with a malformed record, which triggers an exception and later use of an unspecified method, aka "Persist Directory RCE Vulnerability."

Security readout for executives and security teams

This is an old Microsoft PowerPoint vulnerability where a malformed presentation could corrupt memory and potentially run attacker code. Business risk is highest where legacy Office, PowerPoint Viewer, converters, or PowerPoint Web App remain installed or exposed to untrusted files. Exposure is most likely in environments retaining Office 2002, 2003, 2007, 2010, Office for Mac 2004/2008/2011, PowerPoint Viewer, Compatibility Pack, Open XML Converter for Mac, or PowerPoint Web App. Treat as high priority only where legacy Microsoft Office components remain. Modern fully patched environments are less likely exposed, but stale viewer, converter, and web-processing components can persist unnoticed. Mitigation focus: Apply Microsoft guidance and updates from MS11-022 to all affected products.; Inventory and remove unsupported Office, Viewer, converter, and Compatibility Pack installations.; Restrict handling of untrusted PowerPoint files until affected systems are remediated..
