+	<p>The Asterisk project reports:</p>
+	<blockquote cite="http://www.asterisk.org/downloads/security-advisories">;
+	  <p>When audio frames are given to the audio transcoding
+	  support in Asterisk the number of samples are examined
+	  and as part of this a message is output to indicate that
+	  no samples are present. A change was done to suppress
+	  this message for a particular scenario in which the message
+	  was not relevant. This change assumed that information
+	  about the origin of a frame will always exist when in
+	  reality it may not.</p>
+	  <p>This issue presented itself when an RTP packet containing
+	  no audio (and thus no samples) was received. In a particular
+	  transcoding scenario this audio frame would get turned
+	  into a frame with no origin information. If this new frame
+	  was then given to the audio transcoding support a crash
+	  would occur as no samples and no origin information would
+	  be present. The transcoding scenario requires the genericplc
+	  option to be set to enabled (the default) and a transcoding
+	  path from the source format into signed linear and then
+	  from signed linear into another format.</p>
+	  <p>Note that there may be other scenarios that have not
+	  been found which can cause an audio frame with no origin
+	  to be given to the audio transcoding support and thus
+	  cause a crash.</p>
