Exploited in the last 30 days

An Out-of-bounds Write vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker with access to a configured BGP EVPN peer to cause a denial of service via BGP EVPN route processing when the l2vpn-evpn RIB telemetry sensor is subscribed. Successful exploitation can crash rpd and interrupt routing protocols until the daemon restarts and reconverges.
