Debian DLA-1603-1 : suricata security update
medium Nessus Plugin ID 119425
Language:
Synopsis
The remote Debian host is missing a security update.Description
Several issues were found in suricata, an intrusion detection and prevention tool.CVE-2017-7177
Suricata has an IPv4 defragmentation evasion issue caused by lack of a check for the IP protocol during fragment matching.
CVE-2017-15377
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).
CVE-2018-6794
Suricata 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.
TEMP-0856648-2BC2C9 (no CVE assigned yet)
Out of bounds read in app-layer-dns-common.c. On a zero size A or AAAA record, 4 or 16 bytes would still be read.
For Debian 8 'Jessie', these problems have been fixed in version 2.0.7-2+deb8u3.
We recommend that you upgrade your suricata packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
