Prior to version 7.0.16, 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. Version 7.0.16 contains a fix. As a workaround, avoid Lua scripts that call TLS certificate information helpers on untrusted traffic (`TlsGetCertInfo` function), or update scripts to handle missing certificate fields where possible.","published":"2026-09-10T15:17:34.997","modified":"2026-09-10T15:17:34.997","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://forum.suricata.io/t/suricata-8-0-5-and-7-0-16-released/6315"},{"type":"WEB","url":"https://github.com/OISF/suricata/security/advisories/GHSA-vfc5-9844-rmhv"},{"type":"WEB","url":"https://redmine.openinfosecfoundation.org/issues/6286"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T15:17:34.997"}}
