Name of the Vulnerable Software and Affected Versions Suricata versions prior to 7.0.13 Suricata versions prior to 8.0.2

Description Suricata is a network IDS, IPS and NSM engine. Processing large buffers in Lua scripts before versions 7.0.13 and 8.0.2 can lead to a stack overflow. Users utilizing Lua rules and output scripts are potentially affected when handling large buffers, including scenarios where a rule passes a large buffer to a Lua script.

Recommendations Update to Suricata version 7.0.13 or later. Update to Suricata version 8.0.2 or later. Disable Lua rules and output scripts. Set limits, such as stream.depth.reassembly and response-body-limit, to less than half the stack size.
