Descriptions

A NULL Pointer Dereference vulnerability in Juniper Networks Junos OS Evolved on ACX7024, ACX7100-32C and ACX7100-48L allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS).

If a specific IPv4 UDP packet is received and sent to the Routing Engine (RE) packetio crashes and restarts which causes a momentary traffic interruption. Continued receipt of such packets will lead to a sustained DoS.

This issue does not happen with IPv6 packets.

This issue affects Juniper Networks Junos OS Evolved on ACX7024, ACX7100-32C and ACX7100-48L:



* 21.4-EVO versions earlier than 21.4R3-S6-EVO;
* 22.1-EVO versions earlier than 22.1R3-S5-EVO;
* 22.2-EVO versions earlier than 22.2R2-S1-EVO, 22.2R3-EVO;
* 22.3-EVO versions earlier than 22.3R2-EVO.




This issue does not affect Juniper Networks Junos OS Evolved versions earlier than 21.4R1-EVO.

Una vulnerabilidad de desreferencia de puntero NULL en Juniper Networks Junos OS Evolved en ACX7024, ACX7100-32C y ACX7100-48L permite que un atacante no autenticado basado en red provoque una denegación de servicio (DoS). Si se recibe y envía un paquete UDP IPv4 específico al motor de enrutamiento (RE), el paquete falla y se reinicia, lo que provoca una interrupción momentánea del tráfico. La recepción continua de dichos paquetes dará lugar a una DoS sostenida. Este problema no ocurre con los paquetes IPv6. Este problema afecta a Juniper Networks Junos OS Evolved en ACX7024, ACX7100-32C y ACX7100-48L: * Versiones 21.4-EVO anteriores a 21.4R3-S6-EVO; * Versiones 22.1-EVO anteriores a 22.1R3-S5-EVO; * Versiones 22.2-EVO anteriores a 22.2R2-S1-EVO, 22.2R3-EVO; * Versiones 22.3-EVO anteriores a 22.3R2-EVO. Este problema no afecta a las versiones evolucionadas de Juniper Networks Junos OS anteriores a 21.4R1-EVO.
