hostapd: The implementations of EAP-PWD in hostapd EAP Server, when built against a crypto library missing explicit validation...
CVE-2019-9498 is fixed in 3 products on 1 platform, first by hostapd 2:2.6-15ubuntu2.2, released April 10, 2019. It is not reported as exploited. Patch Radar priority: Routine.
The implementations of EAP-PWD in hostapd EAP Server, when built against a crypto library missing explicit validation on imported elements, do not validate the scalar and element values in EAP-pwd-Commit. An attacker may be able to use invalid scalar/element values to complete authentication, gaining session key and network access without needing or learning the password. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.4 are affected. Both hostapd with EAP-pwd support and wpa_supplicant with EAP-pwd support prior to and including version 2.7 are affected.
