+	<h1>Problem Description:</h1>
+	<p>There is a programming error in the Heimdal implementation
+	that used an unauthenticated, plain-text version of the
+	KDC-REP service name found in a ticket.</p>
+	<h1>Impact:</h1>
+	<p>An attacker who has control of the network between a
+	client and the service it talks to will be able to impersonate
+	the service, allowing a successful man-in-the-middle (MITM)
+	attack that circumvents the mutual authentication.</p>
