Name of the Vulnerable Software and Affected Versions OPC Foundation Local Discovery Server (LDS) versions prior to 1.04.402.463

Description The issue is related to a denial of service (DoS) that can be caused by remote attackers sending carefully crafted messages, leading to access of a memory location after the end of a buffer.
