Junos OS Evolved: Connection limits is not being enforced while the resp. rate limit is being enforced

An Improper Restriction of Excessive Authentication Attempts vulnerability in Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to cause a limited Denial of Service (DoS) to the management plane.

When an incoming connection was blocked because it exceeded the connections-per-second rate-limit, the system doesn't consider existing connections anymore for subsequent connection attempts so that the connection limit can be exceeded.
This issue affects Junos OS Evolved:



  *  All versions before 21.4R3-S4-EVO,
  *  22.1-EVO versions before 22.1R3-S3-EVO,
  *  22.2-EVO versions before 22.2R3-S2-EVO, 
  *  22.3-EVO versions before 22.3R2-S1-EVO, 22.3R3-EVO.
