CVE-2024-39541

What is 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).

When conflicting information (IP or ISO addresses) about a node is added to the Traffic Engineering (TE) database and then a subsequent operation attempts to process these, rpd will crash and restart.

• 22.4 versions before 22.4R3-S1,
• 23.2 versions before 23.2R2, 
• 23.4 versions before 23.4R1-S1, 23.4R2, 

This issue does not affect Junos OS versions earlier than 22.4R1.
