Uncommenting AllowOverride FileInfo Options?

[Wazooka]

I seem to have the 500 error in a new rc install. Earlier I noticed the server isn't accepting a 403 redirect file (it just errors with default Fedora page).

Now after searching, I came across this solution posted:

I had to uncomment (in my httpd-vhosts.conf):
AllowOverride FileInfo Options

1. Isn't this a security risk?
2. Will this likely enable the 403 redirect?
