A Reachable Assertion vulnerability in the rpd process of Juniper Networks Junos OS and Junos EVO allows an adjacent attacker to cause a denial of service via an established LDP session when two misconfigured neighbors (or one neighbor duplicated by an L2 loop) advertise the same transport address on a link-protected interface.
