Debian DLA-1603-1 : suricata security update

Medium Nessus Plugin ID 119425


The remote Debian host is missing a security update.


Several issues were found in suricata, an intrusion detection and
prevention tool.


Suricata has an IPv4 defragmentation evasion issue caused by lack of a
check for the IP protocol during fragment matching.


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).


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

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.


Upgrade the affected suricata package.
