Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine.
Mishandling of multiple fragmented packets using the same IP ID value can lead to packet reassembly failure, which can lead to policy bypass. Upgrade to 7.0.6 or 6.0.20. When using af-packet, enable defrag to reduce the scope of the problem.
