      Vypress Tonecast Broadcast Shutdown (Crash)


    " <http://www.vypress.com/products/tonecast/> Vypress Tonecast is
    high-fidelity audio streaming software for local area networks. Vypress
    Tonecast allows you to easily setup and utilise your own radio
    broadcasting over an existing LAN infrastructure without the need for
    additional hardware or complex heaped software systems."

    Vypress Tonecast consists of two modules: a server module that broadcasts
    the audio over the network and a client module which receives the audio.
    The client module does not handle malformed streams correctly and crashes
    immediately both in standalone mode and as a Winamp plugin.


    Vulnerable Systems:
     * Vypress Tonecast version 1.3 and prior

    Upon receiving a malformed stream the client module of Vypress tonecast
    will crash. This behavior is common to both the client program and the
    Winamp plugin.
