CVE-2022-22212
An Allocation of Resources Without Limits or Throttling vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS Evolved allows unauthenticated network based attacker to cause a Denial of Service (DoS). On all Junos Evolved platforms hostbound protocols will be impacted by a high rate of specific hostbound traffic from ports on a PFE. Continued receipt of this amount of traffic will create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS Evolved: 21.2 versions prior to 21.2R3-EVO; 21.3 versions prior to 21.3R2-EVO. This issue does not affect Juniper Networks Junos OS Evolved versions prior to 21.2R1.

En todas las plataformas Junos Evolved, los protocolos de recepción de host estarán afectados por una alta tasa de tráfico específico de host desde los puertos de un PFE. La recepción continuada de esta cantidad de tráfico creará una condición de Denegación de Servicio (DoS) sostenida.
