Calling me a liar is not going to work fine with me. Not at all.
I'm quite nice, and I've accepted quite a few things lately, on this
very mailing-list, but don't push me.

There is no reason to load any DLL from the VLC installation directory
beside libvlccore|libvlc and VLC plugins.
Especially system DLLs. We're not on Linux.
We load only from SYSTEM32 in loadlibrary calls, then we should do the
same in implib.
Or we do none of those.

You forget people using VLC as portable version.

It's not stricto-sensu a strong security issue, since only a
non-installed version can be compromised, or the person has UAC control.
But after those patches, you need SYSTEM control to exploit it.
And yes, there is still the issue of VLC plugins loading, and that needs
Also, it's a good idea to fix all the scenarios, including portable
versions, seeing the number of users.
