CVE-2018-0030
Estado: ModificadaAlta (7.5)—
La recepción de un paquete MPLS específico podría provocar que las tarjetas de línea MPC7/8/9, PTX-FPC3 (FPC-P1, FPC-P2) o PTX1K se cierre inesperadamente y se reinicie. Mediante el envío continuo de paquetes MPLS, un atacante puede cerrar repetidamente las tarjetas de línea o PTX1K, provocando una denegación de servicio (DoS) prolongada.
