Vulnerability CVE-2024-39514

Published: 2024-07-10   Modified: 2024-07-11

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,
