-- CVSS:
10, (AV:N/AC:L/Au:N/C:C/I:C/A:C)

-- Affected Vendors:
Microsoft

-- Affected Products:
Microsoft Office PowerPoint

-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Microsoft Office Powerpoint 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 with the way the application will parse
external objects within an Office Art container. When parsing this
object, the application will append an uninitialized object to a list.
When destroying this object during document close (WM_DESTROY), the
application will access a method that doesn't exist. This can lead to
code execution under the context of the application.
