Descriptions
An improper use of a validation framework when processing incoming genuine BGP packets within Juniper Networks RPD (routing protocols process) daemon allows an attacker to crash RPD thereby causing a Denial of Service (DoS) condition. This framework requires these packets to be passed. By continuously sending any of these types of formatted genuine packets, an attacker can repeatedly crash the RPD process causing a sustained Denial of Service. Authentication to the BGP peer is not required. This issue can be initiated or propagated through eBGP and iBGP and can impact devices in either modes of use as long as the devices are configured to support the compromised framework and a BGP path is activated or active. This issue affects: Juniper Networks Junos OS 16.1 versions 16.1R7-S6 and later versions prior to 16.1R7-S8; 17.3 versions 17.3R2-S5, 17.3R3-S6 and later versions prior to 17.3R3-S8; 17.4 versions 17.4R2-S7, 17.4R3 and later versions prior to 17.4R2-S11, 17.4R3-S2; 18.1 versions 18.1R3-S7 and later versions prior to 18.1R3-S10; 18.2 versions 18.2R2-S6, 18.2R3-S2 and later versions prior to 18.2R2-S7, 18.2R3-S5; 18.2X75 versions 18.2X75-D12, 18.2X75-D32, 18.2X75-D33, 18.2X75-D51, 18.2X75-D60, 18.2X75-D411, 18.2X75-D420 and later versions prior to 18.2X75-D32, 18.2X75-D33, 18.2X75-D420, 18.2X75-D52, 18.2X75-D60, 18.2X75-D65, 18.2X75-D70;(*1) 18.3 versions 18.3R1-S6, 18.3R2-S3, 18.3R3 and later versions prior to 18.3R2-S4, 18.3R3-S2; 18.4 versions 18.4R1-S5, 18.4R2-S4, 18.4R3 and later versions prior to 18.4R1-S7, 18.4R2-S5, 18.4R3-S3(*2); 19.1 versions 19.1R1-S3, 19.1R2 and later versions prior to 19.1R1-S5, 19.1R2-S2, 19.1R3-S2; 19.2 versions 19.2R1-S2, 19.2R2 and later versions prior to 19.2R1-S5, 19.2R2, 19.2R3; 19.3 versions prior to 19.3R2-S3, 19.3R3; 19.4 versions prior to 19.4R1-S2, 19.4R2, 19.4R3; 20.1 versions prior to 20.1R1-S1, 20.1R2. This issue does not affect Junos OS prior to 16.1R1. This issue affects IPv4 and IPv6 traffic.
El uso inapropiado de una comprobación del framework cuando paquetes BGP genuinos entrantes se procesan dentro del demonio (proceso de protocolos de enrutamiento) de Juniper Networks RPD permite a un atacante bloquear el RPD, causando una condición de Denegación de Servicio (DoS). Este framework requiere que estos paquetes sean pasados. Mediante el envío continuo cualquiera de estos tipos de paquetes genuinos formateados, un atacante puede bloquear repetidamente el proceso de RPD causando una Denegación de Servicio sostenida. No es requerida autenticación para el par BGP. Este problema puede ser iniciado o propagado mediante eBGP e iBGP y puede impactar a los dispositivos en cualquiera de los modos de uso, siempre que los dispositivos sean configurados para soportar el framework comprometido y una ruta BGP esté activada o activa.
