   An update that solves one vulnerability and has one errata
   is now available.

Description:

   dbus-1 was 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.
