Advantech ADAM OPC Server ActiveX Control Buffer Overflow Vulnerability

Advantech ADAM OPC Server is prone to a remote buffer-overflow vulnerability because it fails to sufficiently validate user-supplied data. This issue affects an unspecified ActiveX control.

Attackers can exploit this issue to execute arbitrary code within the context of the affected application that uses the ActiveX control (typically Internet Explorer). Failed exploit attempts will result in a denial-of-service condition.
