Descriptions

Memory leak in freeRADIUS 1.1.5 and earlier allows remote attackers to cause a denial of service (memory consumption) via a large number of EAP-TTLS tunnel connections using malformed Diameter format attributes, which causes the authentication request to be rejected but does not reclaim VALUE_PAIR data structures.

Filtración de memoria en freeRADIUS 1.1.5 y anteriores permite a atacantes remotos provocar denegación de servicio (consumo de memoria) a través de un gran número de conexiones de tunel de EAP-TTLS utilizando atributos de formato mal formado de Diameter, lo cual hace que la respuesta de validación sea rechazada pero no recupera la estructura de datos VALUE_PAIR.
