--- Begin Message ---Package: libnss-mymachines Version: 239-6 Severity: important Hi. When libnss-mymachines it automatically adds the respective entries to /etc/nsswitch.conf and it seems to place "mymachines" after "dns". This is IMO bad (and actually even a security hole), as it would resolve DNS names before the mymachine names. The security hole lies in the fact that people will easily trust what runs locally in a VM/container, and e.g. not check SSH keys when connecting to that... however, if dns is resolved first it could point to any machine on the net. The libnss-mymachines itself suggests: It is recommended to place "mymachines" after the "files" or "compat" entry of the /etc/nsswitch.conf lines to make sure that its mappings are preferred over other resolvers such as DNS, but so that /etc/hosts, /etc/passwd and /etc/group based mappings take precedence. Could you please change that and add a NEWS.Debian entry so that people have the chance to catch up? Thanks, Chris.
