CVE-2024-39541

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

• 23.2 versions before 23.2R2, 
• 23.4 versions before 23.4R1-S1, 23.4R2,
