CVE-2024-39514

Summary

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,
