Vulnerability Database

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

before 24.2R2-S1,

• 24.4 versions before 24.4R1-S3, 24.4R2;
