Se ha encontrado una vulnerabilidad en freeRADIUS 1.1.5 y superior. La vulnerabilidad se debe a no tratar correctamente un gran número de conexiones de túnel EATP-TTLS con atributos Diameter mal construidos. Un atacante remoto podría causar una denegación de servicio a través de un gran número de conexiones de túnel EATP-TTLS a través de atributos Diameter mal construidos, causando peticiones de autenticación que serán rechazadas pero no reclamadas por la estructura de datos VALUE_PAIR. |
