'Name' => 'MS15-134 Microsoft Windows Media Center MCL Information Disclosure',
'Description' => %q{
This module exploits a vulnerability found in Windows Media Center. It allows an MCL
file to render itself as a HTML document in the local machine zone by Internet Explorer,
which can be used to leak files on the target machine.
