This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Office 2007. 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 processes a shape record hierarchy. Due to the application not properly checking the types of elements within containers, the application will incorrectly modify a property of the object. This modification can be used to cause memory corruption of the type which can lead to code execution under the context of the application.
