DESCRIPTION:
A vulnerability has been reported in Microsoft PowerPoint 2000, which
can be exploited by malicious people to gain knowledge of sensitive
information.

The vulnerability is caused due to an error within the interaction
between PowerPoint and Internet Explorer when rendering HTML data.
This can be exploited to access objects in the Temporary Internet
Files Folder (TIFF) explicitly by name on a user's system.

Successful exploitation requires that a user e.g. is tricked into
visiting a malicious web site. It is not directly possible to execute
code on the system, but it may provide sensitive information that aids
in further compromise of the vulnerable system.

SOLUTION:
Apply patch.
