Description

Simon McVittie discovered that the fix for CVE-2014-3636 was incorrect, as it did not fully address the underlying denial-of-service vector. This update starts the D-Bus daemon as root initially, so that it can properly raise its file descriptor count.

In addition, this update reverts the auth_timeout change in the previous security update to its old value because the new value causes boot failures on some systems. See the README.Debian file for details how to harden the D-Bus daemon against malicious local users.
