## Overview

A NULL Pointer Dereference vulnerability in the PFE management daemon (evo-pfemand) of Juniper Networks Junos OS Evolved on ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7348, ACX7509 devices allows an unauthenticated, adjacent attacker to cause a 

Denial-of-Service (DoS).

Whenever specific valid multicast traffic is received on any layer 3 interface the evo-pfemand process crashes and restarts.

Continued receipt of specific valid multicast traffic results in a sustained Denial of Service (DoS) attack. 
This issue affects Junos OS Evolved on ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7348, ACX7509: 



  *  from 23.2R2-EVO before 23.2R2-S4-EVO, 
  *  from 23.4R1-EVO before 23.4R2-EVO.


This issue affects IPv4 and IPv6. 

This issue does not affect  Junos OS Evolved ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7348, ACX7509 versions before 23.2R2-EVO.
