** Also affects: iio-sensor-proxy (Debian) via http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=853951 Importance: Unknown Status: Unknown ** Bug watch added: github.com/hadess/iio-sensor-proxy/issues #41 https://github.com/hadess/iio-sensor-proxy/issues/41 ** Also affects: iio-sensor-proxy via https://github.com/hadess/iio-sensor-proxy/issues/41 Importance: Unknown Status: Unknown ** Description changed: The dbus configuration for iio-sensor-proxy allowed any process on the system bus to send an org.freedesktop.DBus.Properties.Set() call to any other process on the system bus, even if the destination process expected to be only accessible by root. https://github.com/hadess/iio-sensor-proxy/commit/e2d81f2 This was fixed in the upstream version 2.1 and in Debian's 2.0-4 (which was autosynced to zesty). I'll prepare debdiff's containing the Debian fix for xenial and yakkety.
