Debian DLA-1603-1 : suricata security update
Medium Nessus Plugin ID 119425
SynopsisThe remote Debian host is missing a security update.
DescriptionSeveral issues were found in suricata, an intrusion detection and
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
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.
