Last modified Jun 17, 2026

CVE-2019-0019 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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. EPSS estimates a 1.14% chance of exploitation in the next 30 days.
