Descriptions

The EAP-pwd peer implementation in hostapd and wpa_supplicant 1.0 through 2.4 does not clear the L (Length) and M (More) flags before determining if a response should be fragmented, which allows remote attackers to cause a denial of service (crash) via a crafted message.

La implementación EAP-pwd peer en hostapd y wpa_supplicant 1.0 hasta 2.4 no limpia los indicadores L (Length) y M (More) antes de determinar si una respuesta debe ser fragmentada, lo que permite a atacantes remotos causar una denegación de servicio (caída) a través de un mensaje manipulado.
