+	<h1>Problem Description:</h1>
+	<p>EAP-pwd implementation in hostapd (EAP server) and wpa_supplicant
+	(EAP peer) does not to validate the received scalar and element values
+	in EAP-pwd-Commit messages properly. This could result in attacks that
+	would be able to complete EAP-pwd authentication exchange without the
+	attacker having to know the used password.</p>
+	<p>See

+	<h1>Impact:</h1>
