Last modified Jun 17, 2026

CVE-2018-14568 is a vulnerability of currently unknown severity. 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).. EPSS estimates a 2.00% chance of exploitation in the next 30 days.
