Descriptions

An Improper Isolation or Compartmentalization vulnerability in the Packet Forwarding Engine (pfe) of Juniper Networks Junos OS on QFX5000 Series and EX Series allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS).

If a specific malformed LACP packet is received by a QFX5000 Series, or an EX4400, EX4100 or EX4650 Series device, an LACP flap will occur resulting in traffic loss.
This issue affects Junos OS on QFX5000 Series, and on EX4400, EX4100 or EX4650 Series:

* 20.4 versions from

20.4R3-S4

before 20.4R3-S8,
* 21.2 versions from

21.2R3-S2

before 21.2R3-S6,
* 21.4 versions from

21.4R2

before 21.4R3-S4,

* 22.1 versions from

22.1R2

before 22.1R3-S3,
* 22.2 versions before 22.2R3-S1,
* 22.3 versions before 22.3R2-S2, 22.3R3,
* 22.4 versions before 22.4R2-S1, 22.4R3.

Una vulnerabilidad de aislamiento o compartimentación incorrecta en el motor de reenvío de paquetes (pfe) de Juniper Networks Junos OS en las series QFX5000 y EX permite que un atacante adyacente no autenticado provoque una denegación de servicio (DoS). Si un paquete LACP específico con formato incorrecto es recibido por un dispositivo de la serie QFX5000 o un dispositivo de la serie EX4400, EX4100 o EX4650, se producirá una falla de LACP que provocará una pérdida de tráfico. Este problema afecta a Junos OS en la serie QFX5000 y en las series EX4400, EX4100 o EX4650: * versiones 20.4 desde 20.4R3-S4 antes de 20.4R3-S8, * versiones 21.2 desde 21.2R3-S2 antes de 21.2R3-S6, * versiones 21.4 de 21.4R2 anterior a 21.4R3-S4, * 22.1 versiones anteriores a 22.1R2 anterior a 22.1R3-S3, * 22.2 versiones anteriores a 22.2R3-S1, * 22.3 versiones anteriores a 22.3R2-S2, 22.3R3, * 22.4 versiones anteriores a 22.4R2-S1, 22.4R3.
