Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.3, specially crafted traffic can cause a heap use after free if the ruleset uses the http.request_header or http.response_header keyword. The vulnerability has been patched in 7.0.3. To work around the vulnerability, avoid the http.request_header and http.response_header keywords.
