+	  <p>Unbound 1.18.0 introduced a feature that removes EDE records from
+	    responses with size higher than the client's advertised buffer size.
+	    Before removing all the EDE records however, it would try to see if
+	    trimming the extra text fields on those records would result in an
+	    acceptable size while still retaining the EDE codes. Due to an
+	    unchecked condition, the code that trims the text of the EDE records
+	    could loop indefinitely. This happens when Unbound would reply with
+	    attached EDE information on a positive reply and the client's buffer
+	    size is smaller than the needed space to include EDE records.
+
+	    The vulnerability can only be triggered when the 'ede: yes' option
+	    is used; non default configuration.</p>
