      "value": "Una vulnerabilidad de falta de sincronizaci\u00f3n en el motor de reenv\u00edo de paquetes (PFE) de Juniper Networks Junos OS en ACX5448 y ACX710 permite que un atacante adyacente no autenticado provoque una denegaci\u00f3n de servicio (DoS). Si una interfaz parpadea mientras el sistema recopila estad\u00edsticas sobre esa interfaz, dos procesos acceden simult\u00e1neamente a un recurso compartido, lo que provoca un bloqueo y reinicio del PFE. Este problema afecta a Junos OS: todas las versiones anteriores a 20.4R3-S9, versiones 21.2 anteriores a 21.2R3-S5, versiones 21.3 anteriores a 21.3R3-S5, versiones 21.4 anteriores a 21.4R3-S4, versiones 22.1 anteriores a 22.1R3-S2, versiones 22.2 anteriores a 22.2 R3-S2, versiones 22.3 anteriores a 22.3R2-S2, 22.3R3, versiones 22.4 anteriores a 22.4R2."
