CVE-2016-10728: Suricata-Ids Suricata

Medium severity, CVSS 5.3. EPSS: 2.1% chance of exploitation in the next 30 days.

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.

Affected products

• Suricata-Ids Suricata: before 3.1.2 (fixed in 3.1.2)
