dbus-1 was updated to version 1.8.12 to fix one security issue.
This security issue was fixed: - Increase dbus-daemons RLIMIT_NOFILE rlimit to 65536 to stop an attacker from exhausting the file descriptors of the system bus (CVE-2014-7824).
Note: This already includes the fix for the regression that was introduced by the first fix for CVE-2014-7824 in 1.8.10.
On fast systems where local users are considered particularly hostile, administrators can return to the 5 second timeout (or any other value in milliseconds) by saving this as /etc/dbus-1/system-local.conf: 5000
