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."}], "lastModified": "2026-09-28T18:44:03.710", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:oisf:suricata:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E23F30EA-1413-4D36-9AB1-852BADD285BE", "versionEndExcluding": "7.0.16"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
