  You have two option

  1 - if you have only trusted users, you may do 'chmod a+s xsane'
  logged as root. So that anyone running it will have root priviledges. So
  will be able to save their picture as say /etc/services ... The backend
  tries to return to effective uid/gid as soon it can, but there is still a risk.

  2 - use saned. The backend will but run by saned with root priviledges,
  but not your frontend.

  Stef
