Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Starting in version 8.0.0 and prior to version 8.0.5, Suricata's IP defragmentation code could deadlock when processing fragmented traffic containing an encapsulated tunnel protocol whose payload is itself fragmented. Version 8.0.5 contains a fix. No known workarounds are available.
