22 | Subject: [PATCH 1/8] hostapd: Avoid key reinstallation in FT handshake | ||
23 | |||
24 | Do not reinstall TK to the driver during Reassociation Response frame | ||
25 | processing if the first attempt of setting the TK succeeded. This avoids | ||
26 | issues related to clearing the TX/RX PN that could result in reusing | ||
27 | same PN values for transmitted frames (e.g., due to CCM nonce reuse and | ||
28 | also hitting replay protection on the receiver) and accepting replayed | ||
29 | frames on RX side. | ||
30 | |||
31 | This issue was introduced by the commit | ||
32 | 0e84c25434e6a1f283c7b4e62e483729085b78d2 ('FT: Fix PTK configuration in | ||
33 | authenticator') which allowed wpa_ft_install_ptk() to be called multiple | ||
34 | times with the same PTK. While the second configuration attempt is | ||
35 | needed with some drivers, it must be done only if the first attempt | ||
36 | failed. | ||

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

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

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

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

2 | |||

4 | |||
5 | wpa: Ignore unauthenticated encrypted EAPOL-Key data | ||
6 | |||
7 | Ignore unauthenticated encrypted EAPOL-Key data in supplicant | ||
8 | processing. When using WPA2, these are frames that have the Encrypted | ||
9 | flag set, but not the MIC flag. | ||
10 | |||
11 | When using WPA2, EAPOL-Key frames that had the Encrypted flag set but | ||
12 | not the MIC flag, had their data field decrypted without first verifying | ||
13 | the MIC. In case the data field was encrypted using RC4 (i.e., when | ||
14 | negotiating TKIP as the pairwise cipher), this meant that | ||
15 | unauthenticated but decrypted data would then be processed. An adversary | ||
16 | could abuse this as a decryption oracle to recover sensitive information | ||
17 | in the data field of EAPOL-Key messages (e.g., the group key). | ||
18 | |||
