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