https://notcve.org/view.php?id=CVE-2019-11555
The EAP-pwd implementation in hostapd (EAP server) before 2.8 and wpa_supplicant (EAP peer) before 2.8 does not validate fragmentation reassembly state properly for a case where an unexpected fragment could be received. This could result in process termination due to a NULL pointer dereference (denial of service). This affects eap_server/eap_server_pwd.c and eap_peer/eap_pwd.c. La implementación de EAP-pwd en hostapd (servidor EAP),versiones anteriores a 2.8, y wpa_supplicant (peer EAP), versiones anteriores a 2.8, no valida correctamente el estado de reensamblado de la fragmentación para un caso en el que se pudiera recibir un fragmento no esperado. Esto podría derivar en la terminación del proceso debido a una derivación de un puntero NULL (denegación de servicio). • http://www.openwall.com/lists/oss-security/2019/04/26/1 https://lists.debian.org/debian-lts-announce/2019/07/msg00030.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5T7G763UECWR7FQXOJVL67PW7C5A3SA4 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DJKZHAT5KPUN26JL77EUH563GAH5XZ5C https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/IQ6P2GI5GSXRNLNIUNPARFZQVDEIGVZD https://seclists.org/bugtraq/2019/M • CWE-476: NULL Pointer Dereference •
CVSS: 7.5EPSS: 1%CPEs: 5EXPL: 0CVE-2019-9496 – An invalid authentication sequence could result in the hostapd process terminating due to missing state validation steps
https://notcve.org/view.php?id=CVE-2019-9496
An invalid authentication sequence could result in the hostapd process terminating due to missing state validation steps when processing the SAE confirm message when in hostapd/AP mode. All version of hostapd with SAE support are vulnerable. An attacker may force the hostapd process to terminate, performing a denial of service attack. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.7 are affected. Una secuencia de autorización no válida puede conllevar a que el proceso de hostapd termine a causa de que faltan pasos de comprobación de estado al procesar el mensaje de confirmación SAE cuando está en el modo hostapd/AP. • http://lists.opensuse.org/opensuse-security-announce/2020-02/msg00021.html http://packetstormsecurity.com/files/152914/FreeBSD-Security-Advisory-FreeBSD-SA-19-03.wpa.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/56OBBOJJSKRTDGEXZOVFSTP4HDSDBLAE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SVMJOFEYBGXZLFF5IOLW67SSOPKFEJP3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TDOZGR3T7FVO5JSZWK2QPR7AOFIEJTIZ https:&# • CWE-287: Improper Authentication CWE-642: External Control of Critical State Data •

https://notcve.org/view.php?id=CVE-2019-9494
The implementations of SAE in hostapd and wpa_supplicant are vulnerable to side channel attacks as a result of observable timing differences and cache access patterns. An attacker may be able to gain leaked information from a side channel attack that can be used for full password recovery. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.7 are affected. Las implementaciones SAE en hostapd y wpa_supplicant son vulnerables a los ataques de canal lateral (side channel) como resultado de diferencias de tiempo observables y patrones de acceso a la caché. Un atacante puede conseguir información filtrada de un ataque de canal lateral (side channel) que pueda ser usado para la recuperación completa de la contraseña. • http://lists.opensuse.org/opensuse-security-announce/2020-02/msg00021.html http://packetstormsecurity.com/files/152914/FreeBSD-Security-Advisory-FreeBSD-SA-19-03.wpa.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/56OBBOJJSKRTDGEXZOVFSTP4HDSDBLAE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SVMJOFEYBGXZLFF5IOLW67SSOPKFEJP3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TDOZGR3T7FVO5JSZWK2QPR7AOFIEJTIZ https:&# • CWE-203: Observable Discrepancy CWE-208: Observable Timing Discrepancy CWE-524: Use of Cache Containing Sensitive Information •
CVSS: 8.1EPSS: 1%CPEs: 7EXPL: 0CVE-2019-9497 – The implementations of EAP-PWD in hostapd EAP Server and wpa_supplicant EAP Peer do not validate the scalar and element values in EAP-pwd-Commit
https://notcve.org/view.php?id=CVE-2019-9497
The implementations of EAP-PWD in hostapd EAP Server and wpa_supplicant EAP Peer do not validate the scalar and element values in EAP-pwd-Commit. This vulnerability may allow an attacker to complete EAP-PWD authentication without knowing the password. However, unless the crypto library does not implement additional checks for the EC point, the attacker will not be able to derive the session key or complete the key exchange. 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. • http://lists.opensuse.org/opensuse-security-announce/2020-02/msg00021.html http://packetstormsecurity.com/files/152914/FreeBSD-Security-Advisory-FreeBSD-SA-19-03.wpa.html https://lists.debian.org/debian-lts-announce/2019/07/msg00030.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/56OBBOJJSKRTDGEXZOVFSTP4HDSDBLAE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SVMJOFEYBGXZLFF5IOLW67SSOPKFEJP3 https://lists.fedoraproject.org/archives/list/p • CWE-287: Improper Authentication CWE-301: Reflection Attack in an Authentication Protocol •

https://notcve.org/view.php?id=CVE-2019-9498
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. Las implementaciones del componente EAP-PWD en hostapd en EAP Server, cuando se construyen contra una biblioteca criptográfica sin comprobación explícita en elementos importados, no comprueban los valores escalares y de elementos en EAP-pwd-Commit. • http://lists.opensuse.org/opensuse-security-announce/2020-02/msg00021.html https://lists.debian.org/debian-lts-announce/2019/07/msg00030.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/56OBBOJJSKRTDGEXZOVFSTP4HDSDBLAE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SVMJOFEYBGXZLFF5IOLW67SSOPKFEJP3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TDOZGR3T7FVO5JSZWK2QPR7AOFIEJTIZ https://seclists.org/bugtraq& • CWE-287: Improper Authentication CWE-346: Origin Validation Error •
