Descriptions

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.7, invalid ALPN in TLS/QUIC traffic when JA4 matching/logging is enabled can lead to Suricata aborting with a panic. This issue has been addressed in 7.0.7. One may disable ja4 as a workaround.

Suricata es un sistema de detección de intrusiones, un sistema de prevención de intrusiones y un motor de monitoreo de seguridad de red. Antes de la versión 7.0.7, un ALPN no válido en el tráfico TLS/QUIC cuando la coincidencia/registro de JA4 está habilitado puede provocar que Suricata cancele la conexión con un mensaje de pánico. Este problema se ha solucionado en la versión 7.0.7. Se puede deshabilitar JA4 como workaround.
