An update that solves one vulnerability and has one security fix can now be installed.

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.
