  "details": "Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. From 8.0.0 until 8.0.6, the SIP parser in rust/src/sip/parser.rs stores request and response body lengths in 16-bit fields. A SIP body larger than 65,536 bytes can truncate the length and prevent frame:request.body or frame:response.body from exposing the complete body to inspection, allowing content in the omitted portion to evade frame-based detection. This issue is fixed in version 8.0.6.",
