CVE-2024-47506

A Deadlock vulnerability in the packet forwarding engine (PFE) of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). When a large amount of traffic is processed by ATP Cloud inspection, a deadlock can occur which will result in a PFE crash and restart. Whether the crash occurs, depends on system internal timing that is outside the attackers control. This issue affects Junos OS on SRX Series: * All versions before 21.3R3-S1, * 21.4 versions before 21.4R3, * 22.1 versions before 22.1R2, * 22.2 versions before 22.2R1-S2, 22.2R2.

Summary		(es) Una vulnerabilidad de bloqueo en el motor de reenvío de paquetes (PFE) de Juniper Networks Junos OS en SRX Series permite que un atacante no autenticado basado en la red provoque una denegación de servicio (DoS). Cuando la inspección de ATP Cloud procesa una gran cantidad de tráfico, puede producirse un bloqueo que provocará un bloqueo y reinicio del PFE. El hecho de que se produzca el bloqueo depende de la sincronización interna del sistema que está fuera del control del atacante. Este problema afecta a Junos OS en SRX Series: * Todas las versiones anteriores a 21.3R3-S1, * Versiones 21.4 anteriores a 21.4R3, * Versiones 22.1 anteriores a 22.1R2, * Versiones 22.2 anteriores a 22.2R1-S2, 22.2R2.
