Serge: I will submit a patch later today. However, I just thought that it's probably better that "allow_setgroups" should be "ignore_setgroups" and we retain the current behaviour (we don't write anything to /proc/$pid/setgroups) -- which allows a user (or runtime) to explicitly disable setgroups even if they would normally have the right to use setgroups.
Does that sound okay to you? I will make the default ignore_setgroups, but IMO we should change the default for `useradd` to (by default) set deny_setgroups. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1729357 Title: unprivileged user can drop supplementary groups To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shadow/+bug/1729357/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
