CVE-2018-0027

Estado: ModificadaMedia (5.9)—

La recepción de un mensaje RSVP PATH manipulado o mal formado podría provocar que el demonio del protocolo de enrutamiento se bloquee o se cierre inesperadamente. Cuando RPD no está disponible, las actualizaciones de enrutamiento no pueden ser procesadas, lo que puede conducir a una caída prolongada de la red. Si RSVP no está habilitado en una interfaz, el problema no puede ser desencadenado mediante esa interfaz. Este problema solo afecta a Juniper Networks Junos OS 16.1 en versiones anteriores a 16.1R3. Este problema no afecta a las versiones de Junos anteriores a la 16.1R1.
