An issue was discovered in Softing OPC UA C++ SDK before 5.70. A malformed OPC/UA message abort packet makes the client crash with a NULL pointer dereference.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
