Never mind, more testing confirmed that it was a local issue. Somehow my /var/lib/docker was trashed. Remove all the directory and restarting from scratch solved the issue. Regards, JC Le 24/01/2018 à 16:06, Jean-Christophe Baptiste a écrit :
Moreover, cat /etc/shadow shows host's users that should not be there (understand: my user)...

Hi guys,
I am afraid of a security issue with Docker. Sorry but I have no other machines to test for now, so it might be a local issue only.
I realized that today when running an Ubuntu container :
% docker run -ti --rm --hostname=ubuntu --net=host ubuntu /bin/bash
It runs a bash shell inside the Ubuntu container.
But, from within the container (screenshot attached):
% apt update # should fail, not finding the command % zypper refresh # unexpectedly, it would work and refresh the host repos!
Of course, this is absolutely abnormal and I am still evaluating the exact impact.
I can tell that the issue was not here one week ago (I have been a quite intensive Docker user for around 2 years).
So I am not sure what is causing this behavior.
Looking forward to reading some feedbacks.
Best regards,
