CVE-2024-33862

Estado: AplazadaAlta (7.5)—

A buffer-management vulnerability in OPC Foundation OPCFoundation.NetStandard.Opc.Ua.Core before 1.05.374.54 could allow remote attackers to exhaust memory resources. It is triggered when the system receives an excessive number of messages from a remote source. This could potentially lead to a denial of service (DoS) condition, disrupting the normal operation of the system.
