CVE-2018-10242: Debian Linux
High severity, CVSS 7.5. EPSS: 1.8% chance of exploitation in the next 30 days.
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.
