Description The issue is related to an Improper Restriction of Communication Channel to Intended Endpoints vulnerability in the NetworkStack agent daemon (nsagentd) of Juniper Networks Junos OS Evolved. This vulnerability allows an unauthenticated network-based attacker to cause limited impact to the availability of the system. If specific packets reach the Routing-Engine (RE), these will be processed normally even if firewall filters are in place, which should have prevented this. This can lead to a limited, increased consumption of resources resulting in a Denial-of-Service (DoS) and unauthorized access.
