<description>
<p>
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.
</p>
</description>
<impact type="normal">
<p>
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.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Speex users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/speex-1.2_beta3_p2"</code>
</resolution>
