Suricata < 7.0.16 Denial of Service Vulnerability

high Nessus Plugin ID 318837

Synopsis

An IDS/IPS solution running on the remote host is affected by a denial of service vulnerability.

Description

The version of OISF Suricata installed on the remote host is prior to 7.0.16. It is, therefore, affected by a vulnerability:

- The Lua TLS certificate information helper could dereference NULL certificate fields when a Lua script requested certificate information for TLS traffic where some certificate fields were absent. Crafted TLS traffic processed by a deployment using affected Lua TLS scripting could crash Suricata, resulting in denial of service. (CVE-2026-45747)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade Suricata to version 7.0.16 or higher.
