DESCRIPTION:
A vulnerability has been reported in Microsoft Windows, which can be
exploited by malicious people to conduct cross-site scripting
attacks.

The vulnerability is caused due to an error in the way the MHTML
(MIME Encapsulation of Aggregate HTML) protocol handler interprets
MIME-formatted requests for content blocks within a document. This
can e.g. be exploited via Internet Explorer to execute arbitrary HTML
and script code in a user's browser session in context of a web site.

SOLUTION:
Enable MHTML protocol lockdown (either manually or using the
available automated "Microsoft Fix it" solution).
