Description

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 7.0.16 and 8.0.5, a protocol change while processing HTTP/2 traffic could lead to type confusion in Suricata. Crafted traffic may cause Suricata to crash, resulting in denial of service. Versions 7.0.16 and 8.0.5 contain a fix. As a workaround, disable HTTP/2 parsing if it is not required.
