Suricata version 4.0.4 incorrectly handles the parsing of the SSH banner. A malformed SSH banner can cause the parsing code to read beyond the allocated data because SSHParseBanner in app-layer-ssh.c lacks a length check.Referenceshttps://suricata-ids.org/2018/07/18/suricata-4-0-5-available/https://lists.debian.org/debian-lts-announce/2019/04/msg00010.html
