Title:
network manager runs dnsmasq as user nobody
Status in network-manager package in Ubuntu:
Confirmed
Bug description:
Network Manager starts dnsmasq to provide better performing DNS
service to the end user; however, it starts dnsmasq as user nobody:
$ ps auwwx | grep [d]nsmasq
nobody 993 0.0 0.1 33072 1120 ? S 12:06 0:00
/usr/sbin/dnsmasq --no-resolv --keep-in-foreground --no-hosts --bind-interfaces
--pid-file=/var/run/sendsigs.omit.d/network-manager.dnsmasq.pid
--listen-address=127.0.1.1 --conf-file=/var/run/nm-dns-dnsmasq.conf
--cache-size=0 --proxy-dnssec
--enable-dbus=org.freedesktop.NetworkManager.dnsmasq
--conf-dir=/etc/NetworkManager/dnsmasq.d
Generally it's bad form from a security perspective to run daemons as
user nobody because a vulnerability in one daemon will possibly allow
it, when compromised, to interfere with another daemon that is also
running as nobody. The preferred solution is to run it under a
service-specific system user.
