CVE-2019-0019: BGP packets can trigger rpd crash when BGP tracing is enabled.
First published: Wed Apr 10 2019(Updated: )
When BGP tracing is enabled an incoming BGP message may cause the Junos OS routing protocol daemon (rpd) process to crash and restart. While rpd restarts after a crash, repeated crashes can result in an extended DoS condition.
