Disable automatic mount by default. Problem solved.
We use a whitelist approach here based
on usbguard daemon (hw centered), and
# cat /etc/dconf/db/local.d/s-media-automount
[org/gnome/desktop/media-handling]
automount=false
automount-open=false
Our scenario is clearly modelled around an user
in front of a GUI. So, it tackles it in different
layers and the actual fs attack vector is not addressed.
Should a "middleware" based on guestmount just check
for the integrity of the fs or keeping it in such
sandbox?
