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." PowerPoint 2002 SP3, 2003 SP3, 2007 SP2, y 2010; Office 2004, 2008, y 2011 para Mac; Open XML File Format Converter para Mac; Office Compatibility Pack para Word, Excel, y PowerPoint 2007 File Formats SP2; PowerPoint Viewer; PowerPoint Viewer 2007 SP2; y PowerPoint Web App, de Microsoft, no comprueba apropiadamente los registros de PersistDirectoryEntry en documentos de PowerPoint, lo que permite a los atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de memoria) por medio de una Diapositiva con un registro malformado, lo que desencadena una excepción y luego el uso de un método no especificado, también se conoce como "Persist Directory RCE Vulnerability." This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Office PowerPoint. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within how the application handles an exception within the PersistDirectoryEntry records when loading a presentation. When an entry points to a container containing a Slide with a malformed record, the application will raise an exception during the loading of the record. • http://osvdb.org/71770 http://www.securityfocus.com/archive/1/517482/100/0/threaded http://www.securityfocus.com/bid/47251 http://www.securitytracker.com/id?1025340 http://www.us-cert.gov/cas/techalerts/TA11-102A.html http://www.vupen.com/english/advisories/2011/0941 http://www.zerodayinitiative.com/advisories/ZDI-11-125 https://docs.microsoft.com/en-us/security-updates/securitybulletins/2011/ms11-022 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval • CWE-20: Improper Input Validation •

Integer underflow in Microsoft PowerPoint 2002 SP3 and 2003 SP3, PowerPoint Viewer SP2, and Office 2004 for Mac allows remote attackers to execute arbitrary code via a crafted PowerPoint document, aka "PowerPoint Integer Underflow Causes Heap Corruption Vulnerability." Desbordamiento de entero en Microsoft PowerPoint 2002 SP3 y 2003 SP3, PowerPoint Viewer SP2, y Office 2004 para Mac permite a atacantes remotos ejecutar código de su elección a través de un documento PowerPoint manipulado, también conocida como "Vulnerabilidad de desbordamiento de entero en PowerPoint causeante de corrupción de pila" This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Office Powerpoint 2003. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the application trusting a value defined within a file. This value will have some arithmetic performed on it, and subsequently be used as a counter for a processing loop. By modifying this value, an attacker can reliably corrupt memory. • http://www.us-cert.gov/cas/techalerts/TA10-313A.html https://docs.microsoft.com/en-us/security-updates/securitybulletins/2010/ms10-088 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A12122 • CWE-189: Numeric Errors •
