+	<h1>Problem Description:</h1>
+	<p>When using WPA2, EAPOL-Key frames with the Encrypted
+	flag and without the MIC flag set, the data field was
+	decrypted first without verifying the MIC. When the dta
+	field was encrypted using RC4, for example, when negotiating
+	TKIP as a pairwise cipher, the unauthenticated but decrypted
+	data was subsequently processed. This opened wpa_supplicant(8)
+	to abuse by decryption and recovery of sensitive information
+	contained in EAPOL-Key messages.</p>
+	<p>See
+	https://w1.fi/security/2018-1/unauthenticated-eapol-key-decryption.txt
+	for a detailed description of the bug.</p>
+	<h1>Impact:</h1>
+	<p>All users of the WPA2 TKIP pairwise cipher are vulnerable
+	to information, for example, the group key.</p>
