CVE-2018-14568: Suricata-Ids Suricata

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

Suricata before 4.0.5 stops TCP stream inspection upon a TCP RST from a server. This allows detection bypass because Windows TCP clients proceed with normal processing of TCP data that arrives shortly after an RST (i.e., they act as if the RST had not yet been received).

Affected products

• Suricata-Ids Suricata: before 4.0.5 (fixed in 4.0.5)
