Late last week Apple rushed to send out and publish a recent patch that affects Apple users regarding the root vulnerability, but the patch had a bug within itself. So they have re-released another patch to fix that.
The patch apple sent out last week was found not to alter the MacOS version, If you had an older MacOS and updated to 10.13.1 the bug was still found and the patch did not work.
Today Apple seemed to have sent out an official permenant fix for this problem. The name for this patch that takes care of the bug is called "IAmRoot" (CVE-2017-13872). You will find the new updated 10.13.2 should now be a good fix for this vulnerability.
I found a table explaning all the fixes they sent out with the new update:
