CVE-2024-30394Network attack vector

RPD crash via crafted EVPN type-5 route

Published Apr 12, 2024 · Updated Aug 2, 2024

Stack-based buffer overflow in the RPD component of Junos OS and Junos OS Evolved allows remote attackers to crash RPD via BGP. RPD mishandles a specific received EVPN type-5 route in a stack buffer, causing the daemon to crash and restart. EVPN must be configured; continuous receipt of the route sustains the service interruption.
