Description
This security bulletin contains information about 1 security vulnerability.
1) Integer overflow (CVE-ID: CVE-2018-10244)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
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.
