Description
This security bulletin contains information about 1 security vulnerability.
1) Input validation error (CVE-ID: CVE-2016-10728)
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.
