Descriptions

The EAP-pwd server and peer implementation in hostapd and wpa_supplicant 1.0 through 2.4 does not validate a fragment is already being processed, which allows remote attackers to cause a denial of service (memory leak) via a crafted message.

La implementación EAP-pwd server and peer en hostapd y wpa_supplicant 1.0 hasta 2.4 no valida si un fragmento ya está siendo procesado, lo que permite a atacantes remotos causar una denegación de servicio (fuga de memoria) a través de un mensaje manipulado.

Kostya Kortchinsky discovered multiple flaws in wpa_supplicant and hostapd. A remote attacker could use these issues to cause wpa_supplicant or hostapd to crash, resulting in a denial of service.
