CVE-2015-0928 1 Oisf 1 Libhtp 2020-03-05 5.0 MEDIUM 7.5 HIGH
libhtp 0.5.15 allows remote attackers to cause a denial of service (NULL pointer dereference).
CVE-2019-10050 1 Oisf 1 Suricata 2019-10-24 5.0 MEDIUM 7.5 HIGH
A buffer over-read issue was discovered in Suricata 4.1.x before 4.1.4. If the input of the decode-mpls.c function DecodeMPLS is composed only of a packet of source address and destination address plus the correct type field and the right number for shim, an attacker can manipulate the control flow, such that the condition to leave the loop is true. After leaving the loop, the network packet has a length of 2 bytes. There is no validation of this length. Later on, the code tries to read at an empty position, leading to a crash.
CVE-2019-17420 2 Oisf, Suricata-ids 2 Libhtp, Suricata 2019-10-16 5.0 MEDIUM 5.3 MEDIUM
In OISF LibHTP before 0.5.31, as used in Suricata 4.1.4 and other products, an HTTP protocol parsing error causes the http_header signature to not alert on a response with a single \r\n ending.
CVE-2019-1010279 1 Oisf 1 Suricata 2019-08-01 5.0 MEDIUM 7.5 HIGH
Open Information Security Foundation Suricata prior to version 4.1.3 is affected by: Denial of Service - TCP/HTTP detection bypass. The impact is: An attacker can evade a signature detection with a specialy formed sequence of network packets. The component is: detect.c (https://github.com/OISF/suricata/pull/3625/commits/d8634daf74c882356659addb65fb142b738a186b). The attack vector is: An attacker can trigger the vulnerability by a specifically crafted network TCP session. The fixed version is: 4.1.3.
CVE-2019-1010251 1 Oisf 1 Suricata 2019-07-23 5.0 MEDIUM 7.5 HIGH
Open Information Security Foundation Suricata prior to version 4.1.2 is affected by: Denial of Service - DNS detection bypass. The impact is: An attacker can evade a signature detection with a specialy formed network packet. The component is: app-layer-detect-proto.c, decode.c, decode-teredo.c and decode-ipv6.c (https://github.com/OISF/suricata/pull/3590/commits/11f3659f64a4e42e90cb3c09fcef66894205aefe, https://github.com/OISF/suricata/pull/3590/commits/8357ef3f8ffc7d99ef6571350724160de356158b). The attack vector is: An attacker can trigger the vulnerability by sending a specifically crafted network request. The fixed version is: 4.1.2.
CVE-2018-10243 1 Oisf 1 Libhtp 2019-04-08 7.5 HIGH 9.8 CRITICAL
htp_parse_authorization_digest in htp_parsers.c in LibHTP 0.5.26 allows remote attackers to cause a heap-based buffer over-read via an authorization digest header.
CVE-2018-1000167 1 Oisf 1 Suricata-update 2018-05-22 9.3 HIGH 7.8 HIGH
OISF suricata-update version 1.0.0a1 contains an Insecure Deserialization vulnerability in the insecure yaml.load-Function as used in the following files: config.py:136, config.py:142, sources.py:99 and sources.py:131. The "list-sources"-command is affected by this bug. that can result in Remote Code Execution(even as root if suricata-update is called by root). This attack appears to be exploitable via a specially crafted yaml-file at https://www.openinfosecfoundation.org/rules/index.yaml. This vulnerability appears to have been fixed in 1.0.0b1.
