Technical details
A reachable assertion vulnerability in the rpd (routing protocol daemon) component of Junos OS allows remote crash via malformed BGP MCAST-VPN (Multicast VPN) updates from a configured eBGP peer. The attack requires a pre-established eBGP peering relationship to send the malicious BGP messages. Successful exploitation crashes rpd, causing routing service disruption.
