Descriptions

The implementations of SAE and EAP-pwd in hostapd and wpa_supplicant 2.x through 2.8 are vulnerable to side-channel attacks as a result of observable timing differences and cache access patterns when Brainpool curves are used. An attacker may be able to gain leaked information from a side-channel attack that can be used for full password recovery.

Las implementaciones de SAE y EAP-pwd en hostapd y wpa_supplicant versiones 2.x hasta la 2.8, son vulnerables a ataques de canal lateral como un resultado de diferencias de tiempo observables y patrones de acceso de caché cuando son usadas curvas Brainpool. Un atacante puede ser capaz de conseguir información filtrada de un ataque de canal lateral que puede usarse para la recuperación completa de la contraseña.
