Description
Gesytec Easylon OPC Server before 2.3.44 does not properly validate server handles, which allows remote attackers to execute arbitrary code or cause a denial of service via unspecified network traffic to the OLE for Process Control (OPC) interface, probably related to free operations on arbitrary memory addresses through certain Remove functions, and read and write operations on arbitrary memory addresses through certain Set, Read, and Write functions.
