Continued receipt of such packets will lead to a sustained DoS.\n\nThis issue does not happen with IPv6 packets.\n\nThis issue affects Juniper Networks Junos OS Evolved on ACX7024, ACX7100-32C and ACX7100-48L:\n\n\n\n  *  21.4-EVO versions earlier than 21.4R3-S6-EVO;\n  *  22.1-EVO versions earlier than 22.1R3-S5-EVO;\n  *  22.2-EVO versions earlier than 22.2R2-S1-EVO, 22.2R3-EVO;\n  *  22.3-EVO versions earlier than 22.3R2-EVO.\n\n\n\n\nThis issue does not affect Juniper Networks Junos OS Evolved versions earlier than 21.4R1-EVO.\n\n\n\n"

      "value": "Una vulnerabilidad de desreferencia de puntero NULL en Juniper Networks Junos OS Evolved en ACX7024, ACX7100-32C y ACX7100-48L permite que un atacante no autenticado basado en red provoque una denegaci\u00f3n de servicio (DoS). Si se recibe y env\u00eda un paquete UDP IPv4 espec\u00edfico al motor de enrutamiento (RE), el paquete falla y se reinicia, lo que provoca una interrupci\u00f3n moment\u00e1nea del tr\u00e1fico. La recepci\u00f3n continua de dichos paquetes dar\u00e1 lugar a una DoS sostenida. Este problema no ocurre con los paquetes IPv6. Este problema afecta a Juniper Networks Junos OS Evolved en ACX7024, ACX7100-32C y ACX7100-48L: * Versiones 21.4-EVO anteriores a 21.4R3-S6-EVO; * Versiones 22.1-EVO anteriores a 22.1R3-S5-EVO; * Versiones 22.2-EVO anteriores a 22.2R2-S1-EVO, 22.2R3-EVO; * Versiones 22.3-EVO anteriores a 22.3R2-EVO. Este problema no afecta a las versiones evolucionadas de Juniper Networks Junos OS anteriores a 21.4R1-EVO."
