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. Afterward the application will use a method off of this malformed object which can lead to code execution under the context of the application.
