Title:
  DBUS API doesn't prevent confined apps from passing paths to files
  without access

Status in the base for Ubuntu mobile products:
  Confirmed
Status in content-hub package in Ubuntu:
  Fix Released
Status in content-hub source package in Vivid:
  Fix Released

Bug description:
  The DBUS API only requires a file path for a content item, it doesn't
  actually require the confined app have access to the file to create a
  transfer.  This could allow a malicious application using the DBUS API
  to export file:///etc/passwd which would then send a copy of that file
  to another app.
