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

Public security bug reported:

Binary package hint: cups

If I put this in cupsd.conf:

<Location />
  Allow all
  Require valid-user
  Order allow,deny
  Allow all
</Location>

I can still view most[1] cups URLs without being prompted for
credentials ([1] in /admin I have another Require directive that
actually works). I validated via /var/log/cups/access_log that my
browser isn't sending any cached credentials. It appears that "Require
valid-user" is completely ignored by cups.

However, if I modify this to "Require user swarren" or "Require user
@SYSTEM", those directives are honored, and I do have to enter
credentials in my browser simply to access /, as I desire.

** Affects: cups (Ubuntu)
