+ <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>
