Subject: [PATCH] admin: Prevent access if any authentication agent isn't
|
|
available
|
|
|
|
The backend currently allows to access and modify files without prompting
|
|
for password if any polkit authentication agent isn't available. This seems
|
|
isn't usually problem, because polkit agents are integral parts of
|
|
graphical environments / linux distributions. The agents can't be simply
|
|
disabled without root permissions and are automatically respawned. However,
|
|
this might be a problem in some non-standard cases.
|
|
|
|
This affects only users which belong to wheel group (i.e. those who are
|
|
already allowed to use sudo). It doesn't allow privilege escalation for
|
|
users, who don't belong to that group.
|
|
|
|
Let's return permission denied error also when the subject can't be
|
|
authorized by any polkit agent to prevent this behavior.
|
|
