Ubuntu Security Notice 3116-1 - It was discovered that DBus incorrectly validated the source of ActivationFailure signals. A local attacker could use this issue to cause a denial of service. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. It was discovered that DBus incorrectly handled certain format strings. A local attacker could use this issue to cause a denial of service, or possibly execute arbitrary code. This issue is only exposed to unprivileged users when the fix for CVE-2015-0245 is not applied, hence this issue is only likely to affect Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. Ubuntu 16.04 LTS and Ubuntu 16.10 have been updated as a preventative measure in the event that a new attack vector for this issue is discovered. Various other issues were also addressed.

On systems with systemd-style service activation, dbus-daemon does not prevent forged ActivationFailure messages from non-root processes. A malicious local user could use this flaw to trick dbus-daemon into thinking that systemd failed to activate a system service, resulting in an error reply back to the requester.
