Microsoft Visual Studio is a product to assist with software development in the Windows operating system. Visual Studio uses Microsoft Active Template Library (ATL), which is a set of template-based C++ classes, to help simplify the programming of Component Object Model (COM) objects.
Microsoft ATL allows command execution due to an erroneous free operation after a program reads a variant from a stream and deletes this variant.
