Description
The vulnerability allows a remote non-authenticated attacker to manipulate data.
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.
Mitigation
Install update from vendor's website.
Vulnerable software versions
Suricata: 3.1.1
