-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Microsoft Office PowerPoint Viewer. User
interaction is required to exploit this vulnerability in that the target
must open a malicious presentation.

The specific flaw exists in the handling of TextBytesAtom records
contained in a PPT file. Due to the lack of bounds checking on the size
argument an unchecked memcpy() copies user data from the file to the
stack, overflowing key exception structures. Exploitation of this
vulnerability can lead to remote compromise of the affected system under
the context of the currently logged in user.

-- Vendor Response:
Microsoft has issued an update to correct this vulnerability. More
