CVE-2011-0655

Microsoft PowerPoint 2007 SP2 y 2010; Office 2004, 2008, y 2011 for 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 no valida adecuadamente los registros imeColorBehaviorContainer Floating Point en documentos PowerPoint, lo que permite a atacantes remotos ejecutar código de su elección o provocar una denegación de servicio (corrupción de memoria) a través de un documento manipulado que contiene un registro incorrecto. También conocida como "Floating Point Techno-color Time Bandit 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 parses a record associated with animation. If a container holds a specific record type, the application will explicitly trust a length used in this record to calculate a pointer for copying floating point numbers to. This can be used to write outside of an allocated buffer and will lead to code execution under the context of the application.
