(Speex: User-assisted execution of arbitrary code)

    oCERT reported that the Speex library does not properly validate the
    'mode' value it derives from Speex streams, allowing for array indexing
    vulnerabilities inside multiple player applications. Within Gentoo,
    xine-lib, VLC, gst-plugins-speex from the GStreamer Good Plug-ins,
    vorbis-tools, libfishsound, Sweep, SDL_sound, and speexdec were found
    to be vulnerable.
  
Impact :

    A remote attacker could entice a user to open a specially crafted Speex
    file or network stream with an application listed above. This might
    lead to the execution of arbitrary code with privileges of the user
    playing the file.
  
Workaround :

    There is no known workaround at this time."
