I'm not sure you understood the point. That being, whether the user
knowingly or unknowingly loads the "malicious" DLL - the application will be
effected the same either way. To that point: it's been possible for over a
decade (and perhaps even longer) so pretending that it's some brand new
threat that needs to be dealt with immediately is foolish.

Zero privileges? So having write access to a share that the user
accesses/loads files from - what do you call that? This is a social
engineering attack - absolutely nothing more.

On a related note: have you also contacted Linus about LD_PRELOAD?
