In a properly configured system with no "unsafe" cgi/php/perl scripts, it
is not possible for a hacker to modify anything on the server, regardless
of ownership.  It is true, however, that any flaw in apache or one of its
scripts will compromise the apache user first.

So yes, it is somewhat risky to have anything on the server owned by the
apache user.  But it is usually a reasonable risk in a tightly controlled
system.  It is probably not a reasonable risk if you have untrusted people
writing cgi/php/perl scripts.
