CVE-2024-47496

A NULL Pointer Dereference vulnerability in the Packet Forwarding Engine (pfe) of Juniper Networks Junos OS allows a local, low-privileged attacker to cause a Denial-of-Service (DoS). When a specific command is executed, the pfe crashes. This will cause traffic forwarding to be interrupted until the system self-recovers. Repeated execution will create a sustained DoS condition. This issue only affects MX Series devices with Line cards MPC1-MPC9. This issue affects: Junos OS on MX Series: * All versions before 21.4R3-S9, * from 22.2 before 22.2R3-S5, * from 22.3 before 22.3R3-S4, * from 22.4 before 22.4R3-S2, * from 23.2 before 23.2R2-S1, * from 23.4 before 23.4R2.

Summary		(es) Una vulnerabilidad de desreferencia de puntero nulo en el motor de reenvío de paquetes (pfe) de Juniper Networks Junos OS permite a un atacante local con pocos privilegios provocar una denegación de servicio (DoS). Cuando se ejecuta un comando específico, el pfe se bloquea. Esto provocará que el reenvío de tráfico se interrumpa hasta que el sistema se recupere por sí solo. La ejecución repetida creará una condición de DoS sostenida. Este problema solo afecta a los dispositivos de la serie MX con tarjetas de línea MPC1-MPC9. Este problema afecta a: Junos OS en la serie MX: * Todas las versiones anteriores a 21.4R3-S9, * desde 22.2 hasta 22.2R3-S5, * desde 22.3 hasta 22.3R3-S4, * desde 22.4 hasta 22.4R3-S2, * desde 23.2 hasta 23.2R2-S1, * desde 23.4 hasta 23.4R2.
