- Published: 2019-04-04 · Updated: 2024-08-05

## Affected

- n/a: version range not reported

## Description

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.
