Bug#271822: PermitRootLogin without-password actually does the same as PermitRootLogin yes



Package: ssh
Version: 1:3.8.1p1-8
Severity: grave

hello,

after i tested it on two differnent boxes, one with up-to-date sarge,
and one with up-to-date sid, i'm quite confident, that the
PermitRootLogin option at sshd_config doesn't understand the
without-password value.

after i changed PermitRootLogin from 'yes' to 'without-password', i was
still able to login from a remote box without any key, and with typing
the root password, not the key passphrase.

i tag this bug as grave, as this is a dangerous security hole. i don't
know how long this appears, but many users may use the feature without
any apprehension that this may open the ssh root account for more
people.

bye
 jonas
