Descriptions

An Improper Validation of Syntactic Correctness of Input vulnerability in Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause Denial of Service (DoS).

On all Junos OS MX Series and SRX Series platforms, when SIP ALG is enabled, and a specific SIP packet is received and processed, NAT IP allocation fails for genuine traffic, which causes Denial of Service (DoS). Continuous receipt of this specific SIP ALG packet will cause a sustained DoS condition.

NAT IP usage can be monitored by running the following command.

user@srx> show security nat resource-usage source-pool <source_pool_name>


Pool name: source_pool_name

Una vulnerabilidad de validación inadecuada de la corrección sintáctica de la entrada en Packet Forwarding Engine (PFE) de Juniper Networks Junos OS permite que un atacante no autenticado basado en la red provoque una denegación de servicio (DoS). En todas las plataformas Junos OS MX Series y SRX Series, cuando SIP ALG está habilitado y se recibe y procesa un paquete SIP específico, la asignación de IP NAT falla para el tráfico genuino, lo que provoca una denegación de servicio (DoS). La recepción continua de este paquete SIP ALG específico provocará una condición DoS sostenida. El uso de NAT IP se puede monitorear ejecutando el siguiente comando. user@srx&gt; show security nat resource-usage source-pool Pool name: source_pool_name.
