+ <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 "&gt;=media-libs/speex-1.2_beta3_p2"</code>
