  script_tag(name:"insight", value:"This update for wpa_supplicant fixes the following issues:

Security issue fixed:

CVE-2019-16275: Fixed an AP mode PMF disconnection protection bypass
 (bsc#1150934).

Non-security issues fixed:

Enable SAE support (jsc#SLE-14992).

Limit P2P_DEVICE name to appropriate ifname size.

Fix wicked wlan (bsc#1156920)

Restore fi.epitest.hostap.WPASupplicant.service (bsc#1167331)

With v2.9 fi.epitest.hostap.WPASupplicant.service is obsolete
 (bsc#1167331)

Fix WLAN config on boot with wicked. (bsc#1166933)

Update to 2.9 release:
 * SAE changes
 - disable use of groups using Brainpool curves
 - improved protection against side channel attacks
[[link moved to references]]
 * EAP-pwd changes
 - disable use of groups using Brainpool curves
 - allow the set of groups to be configured (eap_pwd_groups)
 - improved protection against side channel attacks
[[link moved to references]]
 * fixed FT-EAP initial mobility domain association using PMKSA caching
 (disabled by default for backwards compatibility, can be enabled with
 ft_eap_pmksa_caching=1)
 * fixed a regression in OpenSSL 1.1+ engine loading
 * added validation of RSNE in (Re)Association Response frames
 * fixed DPP bootstrapping URI parser of channel list
 * extended EAP-SIM/AKA fast re-authentication to allow use with FILS
 * extended ca_cert_blob to support PEM format
 * improved robustness of P2P Action frame scheduling
 * added support for EAP-SIM/AKA using anonymous@realm identity
 * fixed Hotspot 2.0 credential selection based on roaming consortium to
 ignore credentials without a specific EAP method
 * added experimental support for EAP-TEAP peer (RFC 7170)
 * added experimental support for EAP-TLS peer with TLS v1.3
 * fixed a regression in WMM parameter configuration for a TDLS peer
 * fixed a regression in operation with drivers that offload 802.1X
 4-way handshake
 * fixed an ECDH operation corner case with OpenSSL
 * SAE changes
 - added support for SAE Password Identifier
 - changed default configuration to enable only groups 19, 20, 21
(i.e., disable groups 25 and 26) and disable all unsuitable groups completely based on REVmd changes
 - do not regenerate PWE unnecessarily when the AP uses the anti-clogging token mechanisms
 - fixed some association cases where both SAE and FT-SAE were enabled
 on both the station and the selected AP
 - started to prefer FT-SAE over SAE AKM if both are enabled
 - started to prefer FT-SAE over FT-PSK if both are enabled
 - fixed FT-SAE when SAE PMKSA caching is used
 - reject use of unsuitable groups based on new implementation guidance in REVmd (allow only FFC groups with prime >= 3072 bits and ECC groups with prime >= 256)
 - minimize timing and memory use differences in PWE derivation
[[link moved to references]] (CVE-2019-9494, bsc#1131868)
 * EAP-pwd changes
 - minimize timing and memory use differences in PWE derivation
[[link moved to references]] ... [Please see the references for more information on the vulnerabilities]");
