Suricata is vulnerable to a Heap Use-after-free. The vulnerability is due to inadequate handling network traffic, particularly when the ruleset utilizes the http.request_header or http.response_header keyword, allows an attacker to still access and potentially manipulate or exploit that freed memory space.
