Descriptions

An Improper Check or Handling of Exceptional Conditions vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS).

An attacker can send specific traffic to the device, which causes the rpd to crash and restart. Continued receipt of this traffic will result in a sustained DoS condition.

This issue only affects devices with an EVPN-VPWS instance with IGMP-snooping enabled.

This issue affects Junos OS:
* All versions before 20.4R3-S10,
* from 21.4 before 21.4R3-S6,
* from 22.1 before 22.1R3-S5,
* from 22.2 before 22.2R3-S3,
* from 22.3 before 22.3R3-S2,
* from 22.4 before 22.4R3,
* from 23.2 before 23.2R2;

Junos OS Evolved:
* All versions before 20.4R3-S10-EVO,
* from 21.4-EVO before 21.4R3-S6-EVO,
* from 22.1-EVO before 22.1R3-S5-EVO,
* from 22.2-EVO before 22.2R3-S3-EVO,
* from 22.3-EVO before 22.3R3-S2-EVO,
* from 22.4-EVO before 22.4R3-EVO,
* from 23.2-EVO before 23.2R2-EVO.

Una vulnerabilidad de verificación o manejo inadecuado de condiciones excepcionales en el demonio de protocolo de enrutamiento (rpd) de Juniper Networks Junos y Junos OS Evolved permite que un atacante adyacente no autenticado provoque una denegación de servicio (DoS). Un atacante puede enviar tráfico específico al dispositivo, lo que provoca que el rpd falle y se reinicie. La recepción continua de este tráfico dará como resultado una condición DoS sostenida. Este problema solo afecta a los dispositivos con una instancia EVPN-VPWS con IGMP-snooping habilitado. Este problema afecta a Junos OS: * Todas las versiones anteriores a 20.4R3-S10, * desde 21.4 anterior a 21.4R3-S6, * desde 22.1 anterior a 22.1R3-S5, * desde 22.2 anterior a 22.2R3-S3, * desde 22.3 anterior a 22.3R3-S2 , * de 22.4 antes de 22.4R3, * de 23.2 antes de 23.2R2; Junos OS Evolved: * Todas las versiones anteriores a 20.4R3-S10-EVO, * desde 21.4-EVO antes de 21.4R3-S6-EVO, * desde 22.1-EVO antes de 22.1R3-S5-EVO, * desde 22.2-EVO antes de 22.2R3- S3-EVO, * desde 22.3-EVO antes de 22.3R3-S2-EVO, * desde 22.4-EVO antes de 22.4R3-EVO, * desde 23.2-EVO antes de 23.2R2-EVO.
