EulerOS installation on the remote host is affected by the following
vulnerability :
- In systemd 240,
bus_open_system_watch_bind_with_description in
shared/bus-util.c (as used by systemd-resolved to
connect to the system D-Bus instance), calls
sd_bus_set_trusted, which disables access controls for
incoming D-Bus messages. An unprivileged user can
exploit this by executing D-Bus methods that should be
restricted to privileged users, in order to change the
system's DNS resolver settings.(CVE-2019-15718)
