Impact
A configured BGP neighbor can crash the routing protocol daemon (rpd), causing a denial of service on the device. An attacker needs an established BGP peering session to send a malicious route update.
Root cause
A NULL pointer dereference occurs in rpd when processing incoming BGP route updates under specific resolution-map routing policies with policy event-tracing turned on.

CVSS v3.1 · CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Fix & remediation
Check advisory JSA112187 for fixed Junos OS and Junos OS Evolved releases. As a temporary workaround, disable policy event-tracing or remove the vulnerable resolution-map routing policy on affected BGP sessions.
AI-suggested. Run it in staging first and check it against the vendor advisory. Why?
