vulnerabilities in multiple player applications.

Speex is an audio compression format designed for speech that is free
of patent restrictions.
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 type="normal">
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.
There is no known workaround at this time.
All Speex users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-libs/speex-1.2_beta3_p2&quot;</code>
