Summary

In Suricata before 4.x, it was possible to trigger lots of redundant checks on the content of crafted network traffic with a certain signature, because of DetectEngineContentInspection in detect-engine-content-inspection.c. The search engine doesn't stop when it should after no match is found; instead, it stops only upon reaching inspection-recursion-limit (3000 by default).

Exploit prediction (EPSS)

1.97% probability of exploitation in the next 30 days, higher than 80% of all scored CVEs.
