You can't fix it. You can always do

        cp file-with-mode-444-perms ./foobar
        chmod +x foobar
        ./foobar

Unix file permission bits aren't really orthogonal, especially r and x.
Even though it may give some admins a deep feeling of satisfaction,
playing with the r and x bits accomplishes nothing in terms of security.
