CVE-2024-39525

AnImproper Handling of Exceptional Conditions vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network-based attacker sending a specific BGP packet to cause rpd to crash and restart, resulting in a Denial of Service (DoS).Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition.

This issue only affects systems withBGP traceoptions enabled and 

requires a BGP session to be already established. Systems withoutBGP traceoptions enabled are not affected by this issue.

This issue affects iBGP and eBGP, and bothIPv4 and IPv6 are affected by this vulnerability.
