Descriptions
Due to the Improper Handling of an Unexpected Data Type in the processing of EVPN routes on Juniper Networks Junos OS and Junos OS Evolved, an attacker in direct control of a BGP client connected to a route reflector, or via a machine in the middle (MITM) attack, can send a specific EVPN route contained within a BGP Update, triggering a routing protocol daemon (RPD) crash, leading to a Denial of Service (DoS) condition. Continued receipt and processing of these specific EVPN routes could create a sustained Denial of Service (DoS) condition. This issue only occurs on BGP route reflectors, only within a BGP EVPN multicast environment, and only when one or more BGP clients have 'leave-sync-route-oldstyle' enabled. This issue affects: Juniper Networks Junos OS 21.3 versions prior to 21.3R3-S2; 21.4 versions prior to 21.4R2-S2, 21.4R3; 22.1 versions prior to 22.1R1-S2, 22.1R3; 22.2 versions prior to 22.2R2. Juniper Networks Junos OS Evolved 21.3 version 21.3R1-EVO and later versions prior to 21.4R3-EVO; 22.1 versions prior to 22.1R1-S2-EVO, 22.1R3-EVO; 22.2 versions prior to 22.2R2-EVO. This issue does not affect: Juniper Networks Junos OS versions prior to 21.3R1. Juniper Networks Junos OS Evolved versions prior to 21.3R1-EVO.
Debido a una administración inapropiada de un tipo de datos inesperado en el procesamiento de rutas EVPN en Juniper Networks Junos OS y Junos OS Evolved, un atacante que tenga el control directo de un cliente BGP conectado a un reflector de rutas, o por medio de un ataque de tipo machine in the middle (MITM), puede enviar una ruta EVPN específica contenida en una actualización de BGP, desencadenando un fallo del demonio del protocolo de enrutamiento (RPD), conllevando a una condición de Denegación de Servicio (DoS). La recepción y el procesamiento continuos de estas rutas EVPN específicas podrían crear una condición de Denegación de Servicio (DoS) sostenida. Este problema sólo es producido en los reflectores de ruta BGP, sólo dentro de un entorno de multidifusión BGP EVPN, y sólo cuando uno o más clientes BGP tienen habilitado "leave-sync-route-oldstyle". Este problema afecta: Juniper Networks Junos OS 21.3 versiones anteriores a 21.3R3-S2; 21.4 versiones anteriores a 21.4R2-S2, 21.4R3; 22.1 versiones anteriores a 22.1R1-S2, 22.1R3; 22.2 versiones anteriores a 22.2R2. Juniper Networks Junos OS Evolved 21.3 versión 21.3R1-EVO y versiones posteriores anteriores a 21.4R3-EVO; 22.1 versiones anteriores a 22.1R1-S2-EVO, 22.1R3-EVO; 22.2 versiones anteriores a 22.2R2-EVO. Este problema no afecta a: Juniper Networks Junos OS versiones anteriores a 21.3R1. Versiones del Juniper Networks Junos OS anteriores a 21.3R1-EVO
