dbus-1, dbus-1-x11 were updated to version 1.8.16 to fix one security issue.

This update fixes the following security issue:
- CVE-2015-0245: Do not allow non-uid-0 processes to send forged
ActivationFailure messages. On Linux systems with systemd
activation, this would allow a local denial of service (bnc#916343).

These additional security hardenings are included:
- Do not allow calls to UpdateActivationEnvironment from uids
other than the uid of the dbus-daemon. If a system service
installs unsafe security policy rules that allow arbitrary
method calls (such as CVE-2014-8148) then this prevents
memory consumption and possible privilege escalation via
UpdateActivationEnvironment.
- Do not allow calls to UpdateActivationEnvironment or the
Stats interface on object paths other than
/org/freedesktop/DBus. Some system services install unsafe
security policy rules that allow arbitrary method calls to
any destination, method and interface with a specified object
path.
