Vulnerability Title
Junos OS Evolved: A high rate of specific hostbound traffic will cause unexpected hostbound traffic delays or drops
Source: NVD (National Vulnerability Database)
Vulnerability Description
An Allocation of Resources Without Limits or Throttling vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS Evolved allows unauthenticated network based attacker to cause a Denial of Service (DoS). On all Junos Evolved platforms hostbound protocols will be impacted by a high rate of specific hostbound traffic from ports on a PFE. Continued receipt of this amount of traffic will create a sustained Denial of Service (DoS) condition.
