+	  <p>It was discovered that libXdmcp before 1.1.3 including used weak
+	    entropy to generate session keys. On a multi-user system using
+	    xdmcp, a local attacker could potentially use information available
+	    from the process list to brute force the key, allowing them to
+	    hijack other users' sessions.</p>
+	  <p>Please note, that since FreeBSD provides arc4random_buf(), it is
+	    unknown if FreeBSD is affected by this vulnerability</p>
