22Subject: [PATCH 1/8] hostapd: Avoid key reinstallation in FT handshake
23
24Do not reinstall TK to the driver during Reassociation Response frame
25processing if the first attempt of setting the TK succeeded. This avoids
26issues related to clearing the TX/RX PN that could result in reusing
27same PN values for transmitted frames (e.g., due to CCM nonce reuse and
28also hitting replay protection on the receiver) and accepting replayed
29frames on RX side.
30
31This issue was introduced by the commit
320e84c25434e6a1f283c7b4e62e483729085b78d2 ('FT: Fix PTK configuration in
33authenticator') which allowed wpa_ft_install_ptk() to be called multiple
34times with the same PTK. While the second configuration attempt is
35needed with some drivers, it must be done only if the first attempt
36failed.

22Subject: [PATCH 2/8] Prevent reinstallation of an already in-use group key
23
24Track the current GTK and IGTK that is in use and when receiving a
25(possibly retransmitted) Group Message 1 or WNM-Sleep Mode Response, do
26not install the given key if it is already in use. This prevents an
27attacker from trying to trick the client into resetting or lowering the
28sequence counter associated to the group key.

22Subject: [PATCH 3/8] Extend protection of GTK/IGTK reinstallation of WNM-Sleep
23 Mode cases
24
25This extends the protection to track last configured GTK/IGTK value
26separately from EAPOL-Key frames and WNM-Sleep Mode frames to cover a
27corner case where these two different mechanisms may get used when the
28GTK/IGTK has changed and tracking a single value is not sufficient to
29detect a possible key reconfiguration.

22Subject: [PATCH 4/8] Prevent installation of an all-zero TK
23
24Properly track whether a PTK has already been installed to the driver
25and the TK part cleared from memory. This prevents an attacker from
26trying to trick the client into installing an all-zero TK.
27
28This fixes the earlier fix in commit
29ad00d64e7d8827b3cebd665a0ceb08adabf15e1e ('Fix TK configuration to the
30driver in EAPOL-Key 3/4 retry case') which did not take into account
31possibility of an extra message 1/4 showing up between retries of
32message 3/4.

22Subject: [PATCH 5/8] Fix PTK rekeying to generate a new ANonce
23
24The Authenticator state machine path for PTK rekeying ended up bypassing
25the AUTHENTICATION2 state where a new ANonce is generated when going
26directly to the PTKSTART state since there is no need to try to
27determine the PMK again in such a case. This is far from ideal since the
28new PTK would depend on a new nonce only from the supplicant.
29
30Fix this by generating a new ANonce when moving to the PTKSTART state
31for the purpose of starting new 4-way handshake to rekey PTK.

22Subject: [PATCH 6/8] TDLS: Reject TPK-TK reconfiguration
23
24Do not try to reconfigure the same TPK-TK to the driver after it has
25been successfully configured. This is an explicit check to avoid issues
26related to resetting the TX/RX packet number. There was already a check
27for this for TPK M2 (retries of that message are ignored completely), so
28that behavior does not get modified.
29
30For TPK M3, the TPK-TK could have been reconfigured, but that was
31followed by immediate teardown of the link due to an issue in updating
32the STA entry. Furthermore, for TDLS with any real security (i.e.,
33ignoring open/WEP), the TPK message exchange is protected on the AP path
34and simple replay attacks are not feasible.
35
36As an additional corner case, make sure the local nonce gets updated if
37the peer uses a very unlikely "random nonce" of all zeros.

26Mode Response if WNM-Sleep Mode has not been used') started ignoring the
27response when no WNM-Sleep Mode Request had been used during the
28association. This can be made tighter by clearing the used flag when
29successfully processing a response. This adds an additional layer of
30protection against unexpected retransmissions of the response frame.

22Subject: [PATCH 8/8] FT: Do not allow multiple Reassociation Response frames
23
24The driver is expected to not report a second association event without
25the station having explicitly request a new association. As such, this
26case should not be reachable. However, since reconfiguring the same
27pairwise or group keys to the driver could result in nonce reuse issues,
28be extra careful here and do an additional state check to avoid this
29even if the local driver ends up somehow accepting an unexpected
30Reassociation Response frame.

10
11When using WPA2, EAPOL-Key frames that had the Encrypted flag set but
12not the MIC flag, had their data field decrypted without first verifying
13the MIC. In case the data field was encrypted using RC4 (i.e., when
14negotiating TKIP as the pairwise cipher), this meant that
15unauthenticated but decrypted data would then be processed. An adversary
16could abuse this as a decryption oracle to recover sensitive information
17in the data field of EAPOL-Key messages (e.g., the group key).
