Una vulnerabilidad de desbordamiento de búfer basado en pila en el demonio del protocolo de enrutamiento (rpd) de Juniper Networks Junos OS y Junos OS Evolved permite a un atacante con acceso a una sesión de peering BGP configurada provocar una denegación de servicio mediante el envío de un atributo de ruta BGP manipulado, que se procesa mientras hay activa una suscripción de telemetría en tiempo real (streaming) de la RIB de BGP.

Este problema no afecta a las versiones de Junos OS anteriores a 22.1R1. Este problema no afecta a las versiones de Junos OS Evolved anteriores a 22.1R1-EVO.
