CVE-2018-10244: Oisf suricata integer overflow vulnerability

Oisf · Suricata

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.
