The dll is no longer supported.\n RPC: Using rpcns4.dll. The resulting pointer points to unmapped memory and crashes when it gets dereferenced it as we see later in the code.\n \n \n 67a4bb51 lea eax, \n \n\nAt this point edx, eax+0x4 contains the following:\n\n**edx:**\n \n \n 0000beef g\n RPC: Using rpcns4.dll. At this point EDX is controlled by the user and since there is not a check that compares the user input size to make sure is less or equal than the application can receive and process. EDX is the Address Item Length size, EAX points to the start of the Address Item and EAX+0x4 points to the start of the Address Item Data. \n \n\nThe vulnerability happens at address `67a4bb51`.
