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. • https://github.com/OISF/suricata/pull/3590/commits/11f3659f64a4e42e90cb3c09fcef66894205aefe https://github.com/OISF/suricata/pull/3590/commits/8357ef3f8ffc7d99ef6571350724160de356158b https://redmine.openinfosecfoundation.org/issues/2736 • CWE-20: Improper Input Validation •

An issue was discovered in Suricata 4.1.x before 4.1.4. If the input of the function SSHParseBanner is composed only of a \n character, then the program runs into a heap-based buffer over-read. This occurs because the erroneous search for \r results in an integer underflow. Se descubrió un problema en Suricata versión 4.1.x anterior a la 4.1.4. Si la entrada de la función SSHParseBanner está compuesta sólo por un carácter, entonces el programa se ejecuta en una sobrelectura de búfer basada en pilas. • https://lists.openinfosecfoundation.org/pipermail/oisf-announce https://suricata-ids.org/2019/04/30/suricata-4-1-4-released • CWE-125: Out-of-bounds Read CWE-191: Integer Underflow (Wrap or Wraparound) •

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. • https://lists.openinfosecfoundation.org/pipermail/oisf-announce https://suricata-ids.org/2019/04/30/suricata-4-1-4-released • CWE-125: Out-of-bounds Read •

Suricata version 4.0.4 incorrectly handles the parsing of an EtherNet/IP PDU. A malformed PDU can cause the parsing code to read beyond the allocated data because DecodeENIPPDU in app-layer-enip-commmon.c has an integer overflow during a length check. La versión 4.0.4 de Suricata gestiona de manera incorrecta el análisis de las unidades de datos de protocolo (PDU) de EtherNet/IP. Un PDU mal formado puede hacer que el código de análisis lea más allá de los datos asignados porque DecodeENIPPDU en app-layer-enip-commmon.c presenta un desbordamiento de enteros durante una comprobación de longitud. • https://suricata-ids.org/2018/07/18/suricata-4-0-5-available • CWE-190: Integer Overflow or Wraparound •

Suricata version 4.0.4 incorrectly handles the parsing of the SSH banner. A malformed SSH banner can cause the parsing code to read beyond the allocated data because SSHParseBanner in app-layer-ssh.c lacks a length check. La versión 4.0.4 de Suricata gestiona de manera incorrecta el análisis del banner SSH. Un banner SSH mal formado puede hacer que el código de análisis lea más allá de los datos asignados porque SSHParseBanner en app-layer-ssh.c carece de comprobación de longitud. • https://lists.debian.org/debian-lts-announce/2019/04/msg00010.html https://suricata-ids.org/2018/07/18/suricata-4-0-5-available • CWE-125: Out-of-bounds Read •
