 In tor.spec.in we do
 {{{
 # Older tor RPMS used a different username for the tor daemon.
 # Make sure the runtime data have the right ownership.
 %__chown -R %{toruser}.%{torgroup} %{_localstatedir}/{lib,log,run}/%{name}
 }}}

 That -R will let an attacker who gets control of the _tor user get control
 of other files on the system.

 The fix is to remove the -R from that line.

 The downside is that we won't actually get the smooth upgrade that the
 comment implies. I wonder if these "older Tor rpms" still exist?
