CVE-2025-60003Network attack vector

rpd crash via optional transitive BGP attributes

Published Jan 15, 2026 · Updated Jan 15, 2026

Buffer over-read in Juniper Networks Junos OS and Junos OS Evolved allows remote attackers to crash and restart rpd through BGP updates. The routing daemon reads beyond the attribute buffer while processing specific optional transitive attributes for advertisement to another peer. Reachability requires an established BGP session and at least one non-4-byte-AS-capable peer, a nondefault condition that interrupts routing while rpd restarts.
