Not without looking at its source code. Here's its patch:

http://developer.momonga-linux.org/viewvc/trunk/pkgs/dbus/dbus-0.61-selinux-avc-audit.patch?r1=13947&r2=13946&pathrev=13947&view=patch

nscd also does the same trick, but its coded in glibc style.

No, there's an intricate dance regarding setuid, prctl, & capabilities
that must be followed exactly or bad things can happen.
