Junos OS and Junos OS Evolved: Specific BGP EVPN update message causes rpd crash

Published Oct 9, 2025

Description

An Improper Check for Unusual or Exceptional Conditions vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial-Of-Service (DoS).

When an affected system receives a specific BGP EVPN update message over an established BGP session, this causes an rpd crash and restart.

A BGP EVPN configuration is not necessary to be vulnerable. If peers are not configured to send BGP EVPN updates to a vulnerable device, then this issue can't occur.

This issue affects iBGP and eBGP, over IPv4 and IPv6.

This issue affects: Junos OS: * 23.4 versions from

23.4R2-S3 before 23.4R2-S5, * 24.2 versions from

24.2R2

before 24.2R2-S1, * 24.4 versions before 24.4R1-S3, 24.4R2;

Junos OS Evolved: * 23.4-EVO versions from 23.4R2-S2-EVO before 23.4R2-S5-EVO, * 24.2-EVO versions from 24.2R2-EVO before 24.2R2-S1-EVO, * 24.4-EVO versions before 24.4R1-S3-EVO, 24.4R2-EVO.
