CVE-2019-0001

Receipt of a malformed packet on MX Series devices with dynamic vlan configuration can trigger an uncontrolled recursion loop in the Broadband Edge subscriber management daemon (bbe-smgd), and lead to high CPU usage and a crash of the bbe-smgd service. Repeated receipt of the same packet can result in an extended denial of service condition for the device. Affected releases are Juniper Networks Junos OS: 16.1 versions prior to 16.1R7-S1; 16.2 versions prior to 16.2R2-S7; 17.1 versions prior to 17.1R2-S10, 17.1R3; 17.2 versions prior to 17.2R3; 17.3 versions prior to 17.3R3-S1; 17.4 versions prior to 17.4R2; 18.1 versions prior to 18.1R3; 18.2 versions prior to 18.2R2.

La recepción de un paquete mal formado en dispositivos MX Series con una configuración vlan dinámica puede desencadenar un bucle de recursión no controlado en el demonio de gestión de suscriptores Broadband Edge (bbe-smgd) y conducir a un alto uso de CPU y el cierre inesperado del servicio bbe-smgd. La recepción repetida del mismo paquete puede resultar en una condición de denegación de servicio (DoS) extendida para los dispositivos. Las versiones afectadas son Juniper Networks Junos OS: 16.1 en versiones anteriores a la 16.1R7-S1; 16.2 en versiones anteriores a la 16.2R2-S7; 17.1 en versiones anteriores a la 17.1R2-S10, 17.1R3; 17.2 en versiones anteriores a la 17.2R3; 17.3 en versiones anteriores a la 17.3R3-S1; 17.4 en versiones anteriores a la 17.4R2; 18.1 en versiones anteriores a la 18.1R3 y 18.2 en versiones anteriores a la 18.2R2.
