Description:

This update for hostapd fixes the following issues:

- Fix KRACK attacks on the AP side (boo#1063479, CVE-2017-13078, CVE-2017-13079, CVE-2017-13080, CVE-2017-13081, CVE-2017-13087, CVE-2017-13088):

Hostap was updated to upstream release 2.6

* fixed EAP-pwd last fragment validation [http://w1.fi/security/2015-7/] (CVE-2015-5314) * fixed WPS configuration update vulnerability with malformed passphrase [http://w1.fi/security/2016-1/] (CVE-2016-4476) * extended channel switch support for VHT bandwidth changes * added support for configuring new ANQP-elements with anqp_elem=<InfoID>:<hexdump of payload> * fixed Suite B 192-bit AKM to use proper PMK length (note: this makes old releases incompatible with the fixed behavior) * added no_probe_resp_if_max_sta=1 parameter to disable Probe Response frame sending for not-associated STAs if max_num_sta limit has been reached * added option (-S as command line argument) to request all interfaces to be started at the same time * modified rts_threshold and fragm_threshold configuration parameters to allow -1 to be used to disable RTS/fragmentation * EAP-pwd: added support for Brainpool Elliptic Curves (with OpenSSL 1.0.2 and newer) * fixed EAPOL reauthentication after FT protocol run * fixed FTIE generation for 4-way handshake after FT protocol run * fixed and improved various FST operations * TLS server - support SHA384 and SHA512 hashes - support TLS v1.2 signature algorithm with SHA384 and SHA512 - support PKCS #5 v2.0 PBES2 - support PKCS #5 with PKCS #12 style key decryption - minimal support for PKCS #12 - support OCSP stapling (including ocsp_multi) * added support for OpenSSL 1.1 API changes - drop support for OpenSSL 0.9.8 - drop support for OpenSSL 1.0.0 * EAP-PEAP: support fast-connect crypto binding * RADIUS - fix Called-Station-Id to not escape SSID - add Event-Timestamp to all Accounting-Request packets - add Acct-Session-Id to Accounting-On/Off - add Acct-Multi-Session-Id ton Access-Request packets - add Service-Type (= Frames) - allow server to provide PSK instead of passphrase for WPA-PSK Tunnel_password case - update full message for interim accounting updates - add Acct-Delay-Time into Accounting messages - add require_message_authenticator configuration option to require CoA/Disconnect-Request packets to be authenticated * started to postpone WNM-Notification frame sending by 100 ms so that the STA has some more time to configure the key before this frame is received after the 4-way handshake * VHT: added interoperability workaround for 80+80 and 160 MHz channels * extended VLAN support (per-STA vif, etc.) * fixed PMKID derivation with SAE * nl80211 - added support for full station state operations - fix IEEE 802.1X/WEP EAP reauthentication and rekeying to use unencrypted EAPOL frames * added initial MBO support; number of extensions to WNM BSS Transition Management * added initial functionality for location related operations * added assocresp_elements parameter to allow vendor specific elements to be added into (Re)Association Response frames * improved Public Action frame addressing - use Address 3 = wildcard BSSID in GAS response if a query from an unassociated STA used that address - fix TX status processing for Address 3 = wildcard BSSID - add gas_address3 configuration parameter to control Address 3 behavior * added command line parameter -i to override interface parameter in hostapd.conf * added command completion support to hostapd_cli * added passive client taxonomy determination (CONFIG_TAXONOMY=y compile option and "SIGNATURE <addr>" control interface command) * number of small fixes

hostapd was updated to upstream release 2.5

* (CVE-2015-1863) is fixed in upstream release 2.5

* fixed WPS UPnP vulnerability with HTTP chunked transfer encoding [http://w1.fi/security/2015-2/] (CVE-2015-4141 boo#930077) * fixed WMM Action frame parser [http://w1.fi/security/2015-3/] (CVE-2015-4142 boo#930078) * fixed EAP-pwd server missing payload length validation [http://w1.fi/security/2015-4/] (CVE-2015-4143, CVE-2015-4144, CVE-2015-4145, boo#930079) * fixed validation of WPS and P2P NFC NDEF record payload length [http://w1.fi/security/2015-5/] * nl80211: - fixed vendor command handling to check OUI properly * fixed hlr_auc_gw build with OpenSSL * hlr_auc_gw: allow Milenage RES length to be reduced * disable HT for a station that does not support WMM/QoS * added support for hashed password (NtHash) in EAP-pwd server * fixed and extended dynamic VLAN cases * added EAP-EKE server support for deriving Session-Id * set Acct-Session-Id to a random value to make it more likely to be unique even if the device does not have a proper clock * added more 2.4 GHz channels for 20/40 MHz HT co-ex scan * modified SAE routines to be more robust and PWE generation to be stronger against timing attacks * added support for Brainpool Elliptic Curves with SAE * increases maximum value accepted for cwmin/cwmax * added support for CCMP-256 and GCMP-256 as group ciphers with FT * added Fast Session Transfer (FST) module * removed optional fields from RSNE when using FT with PMF (workaround for interoperability issues with iOS 8.4) * added EAP server support for TLS session resumption * fixed key derivation for Suite B 192-bit AKM (this breaks compatibility with the earlier version) * added mechanism to track unconnected stations and do minimal band steering * number of small fixes
