Candidate: CVE-2018-6794 PublicDate: 2018-02-07 05:29:00 UTC References: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-6794 https://redmine.openinfosecfoundation.org/issues/2427 https://github.com/OISF/suricata/pull/3202/commits/e1ef57c848bbe4e567d5d4b66d346a742e3f77a1 Description: Suricata before 4.0.4 is prone to an HTTP detection bypass vulnerability in detect.c and stream-tcp.c. If a malicious server breaks a normal TCP flow and sends data before the 3-way handshake is complete, then the data sent by the malicious server will be accepted by web clients such as a web browser or Linux CLI utilities, but ignored by Suricata IDS signatures. This mostly affects IDS signatures for the HTTP protocol and TCP stream content; signatures for TCP packets will inspect such network traffic as usual.
