An issue was discovered in dbus >= 1.3.0 before 1.12.18. The DBusServer in
libdbus, as used in dbus-daemon, leaks file descriptors when a message
exceeds the per-message file descriptor limit. A local attacker with access
to the D-Bus system bus or another system service’s private AF_UNIX socket
could use this to make the system service reach its file descriptor limit,
denying service to subsequent D-Bus clients.
