This is the sort of thing that system back-ups are useful for... also
the package managers generally have functionality for this now, and
there are some system tools that you can use to verify the ownerships
and permissions of installed packages.  I think you might get what you
want with:

  yum verify-all

But I haven't run Fedora in quite a while and my memory is very hazy.

Though to be honest the way I generally handle this kind of problem
these days is to keep /home on a separate partition, and just do a
fresh install when things go bad (which, since this is Linux, happens
exceedingly rarely).
