CVE-2017-15377: Openinfosecfoundation Suricata

High severity, CVSS 7.5. EPSS: 2% chance of exploitation in the next 30 days.

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).

Affected products

• Openinfosecfoundation Suricata: up to and including 3.2.4
