Junos OS Evolved: ACX7024, ACX7100-32C and ACX7100-48L: Traffic stops when a specific IPv4 UDP packet is received by the RE

A NULL Pointer Dereference vulnerability in Juniper Networks Junos OS Evolved on ACX7024, ACX7100-32C and ACX7100-48L allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS).
