*** This bug is a security vulnerability ***

Public security bug reported:

When SNAP_USER_DATA changed to be $HOME/snap from $HOME/snaps, the
corresponding change was not made to the home interface security policy,
resulting in snaps using the home interface having full access to
SNAP_USER_DATA of other snaps.
