Impact
A BGP-LS peer can crash the routing protocol daemon (rpd), causing a complete denial of service across routing functions. The attacker requires network access as an established, configured BGP-LS peer.
Root cause
The routing protocol daemon hits a reachable assertion failure when processing malformed or crafted BGP-LS Link NLRI advertisements.
Affected systems
Juniper Networks Junos OS and Junos OS Evolved (specific versions not listed — check vendor advisory JSA112187).
CVSS v3.1 · CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Fix & remediation
Upgrade to the fixed Junos release specified in JSA112187; as a workaround, disable or restrict BGP-LS peering to fully trusted neighbors.
AI-suggested. Run it in staging first and check it against the vendor advisory. Why?
