This issue is triggered when the packets attempt to initiate a BGP connection before a BGP session is successfully established. Continued receipt of these specific BGP packets will cause a sustained Denial of Service condition. This issue is triggerable in both iBGP and eBGP deployments.

Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network-based attacker to send specific genuine BGP packets to a device configured with BGP to cause a Denial of Service (DoS) by crashing the Routing Protocol Daemon (rpd). This issue is triggered when the packets attempt to initiate a BGP connection before a BGP session is successfully established. Continued receipt of these specific BGP packets will cause a sustained Denial of Service condition. This issue is triggerable in both iBGP and eBGP deployments.
