Published Jul 23, 2018 CVSS 3.0 · 7.5 High EPSS 2.0% KEV · Not listed

Description

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).
