The pfemand process is responsible for packet forwarding on the device. By continuously sending the packet flood, an attacker can repeatedly crash the pfemand process causing a sustained Denial of Service. This issue can only be triggered by traffic sent to the device. Transit traffic does not cause this issue. This issue affects all version of Junos OS Evolved prior to 19.1R1-EVO."}, {"lang": "es", "value": "Una vulnerabilidad en Juniper Networks Junos OS Evolved, puede permitir a un atacante causar una Denegaci\u00f3n de servicio (DoS) mediante el env\u00edo de una alta tasa de paquetes espec\u00edficos hacia el dispositivo, resultando en un bloqueo del proceso pfemand. El proceso pfemand es responsable del reenv\u00edo de paquetes en el dispositivo.
