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).

If a specific IPv4 UDP packet is received and sent to the Routing Engine (RE) packetio crashes and restarts which causes a momentary traffic interruption. Continued receipt of such packets will lead to a sustained DoS.

This issue does not happen with IPv6 packets.

This issue affects Juniper Networks Junos OS Evolved on ACX7024, ACX7100-32C and ACX7100-48L:

21.4-EVO versions earlier than 21.4R3-S6-EVO;
22.1-EVO versions earlier than 22.1R3-S5-EVO;
22.2-EVO versions earlier than 22.2R2-S1-EVO, 22.2R3-EVO;
22.3-EVO versions earlier than 22.3R2-EVO.

This issue does not affect Juniper Networks Junos OS Evolved versions earlier than 21.4R1-EVO.
