CVE-2016-10728: Suricata-ids suricata improper input validation vulnerability

SSuricata Ids · Suricata

An issue was discovered in Suricata before 3.1.2. If an ICMPv4 error packet is received as the first packet on a flow in the to_client direction, it confuses the rule grouping lookup logic. The toclient inspection will then continue with the wrong rule group. This can lead to missed detection.
