+	  <p>Multiple versions of Open vSwitch are vulnerable to remote buffer
+	    overflow attacks, in which crafted MPLS packets could overflow the
+	    buffer reserved for MPLS labels in an OVS internal data structure.
+	    The MPLS packets that trigger the vulnerability and the potential for
+	    exploitation vary depending on version:</p>
+	<p>Open vSwitch 2.1.x and earlier are not vulnerable.</p>
+	<p>In Open vSwitch 2.2.x and 2.3.x, the MPLS buffer overflow can be
+	  exploited for arbitrary remote code execution.</p>
+	<p>In Open vSwitch 2.4.x, the MPLS buffer overflow does not obviously lead
+	  to a remote code execution exploit, but testing shows that it can allow a
+	  remote denial of service.  See the mitigation section for details.</p>
+	<p>Open vSwitch 2.5.x is not vulnerable.</p>
