Title:
  Guest account can read/write in /media/

Status in “lightdm” package in Ubuntu:
  Fix Released

Bug description:
  The guest account can everything under /media/.
  Is the guest account really supposed to be able to access and read all the files on the host computer?

  If yes, then is the guest account really really supposed to be able to write to /media/ ?
  Shouldn't the guest be limited to his temporary home in /tmp/ ?
