How can I recursively verify the permissions within a given subdirectory?

I'd like to verify that nothing within /foo/bar is chmod 777. Or, alternatively, I'd like to make sure that nothing within /foo/bar us owned by user1 or in group1.

Is there any way I can recursively verify the permissions within a given subdirectory to make sure there aren't any security holes?

Notice that I do not want to change all the permissions to something specific, nor do I want to change the owner to something specific, so a recursive chmod or chown won't do it...

Thanks!
