Descriptions

On SRX5000 Series devices, if 'set security zones security-zone <zone> tcp-rst' is configured, the flowd process may crash when a specific TCP packet is received by the device and triggers a new session. The process restarts automatically. However, receipt of a constant stream of these TCP packets may result in an extended Denial of Service (DoS) condition on the device. This issue affects Juniper Networks Junos OS: 18.2R3 on SRX 5000 Series; 18.4R2 on SRX 5000 Series; 19.2R1 on SRX 5000 Series.

En los dispositivos de la Serie SRX5000, si se configura "set security zones security-zone (zone) tcp-rst", el proceso flowd puede bloquearse cuando un paquete TCP específico es recibido por el dispositivo y desencadena una nueva sesión. El proceso se reinicia automáticamente. Sin embargo, la recepción de un flujo constante de estos paquetes TCP puede resultar en una condición de Denegación de Servicio (DoS) extendida en el dispositivo. Este problema afecta a Juniper Networks Junos OS: versión 18.2R3 en la serie SRX 5000; versión 18.4R2 en la serie SRX 5000; versión 19.2R1 en la serie SRX 5000.
