Critical

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions Suricata version 4.0.4

Description The issue arises from incorrect handling of EtherNet/IP PDU parsing, which can lead to the parsing code reading beyond the allocated data due to an integer overflow during a length check in the DecodeENIPPDU function in app-layer-enip-commmon.c. This occurs when a malformed PDU is encountered.

Recommendations For Suricata version 4.0.4, consider disabling the DecodeENIPPDU function in app-layer-enip-commmon.c as a temporary workaround until a patch is available. Restrict access to the EtherNet/IP PDU parsing functionality to minimize the risk of exploitation.
