About the Subgraph attack:
1. The main problem that @micahflee exploited is the unfortunate decision made by Subgraph OS to keep Gnome/Nautilus in the TCB *and* letting this complex software process *untrusted* files,
2. The specific Nautilus bug (handling of .desktop files) is just *one* example of what could go wrong in this case,
3. We can think of other potential problems (e.g. Thumbnails processing)
