Re: Important Security Update
This build number after the version number (17B1002) reflects the updated system.

Re: Important Security Update
Some users are apparently experiencing file sharing issues after installing the security update. Here's an explanation and the fix:

I would only recommend this if you are experiencing the file sharing issue discussed.

Re: Important Security Update
Security Update 2017-001 is now being installed automatically, even if you manually installed previously. It changes the High Sierra build number to 17B1003. This apparently fixes the file sharing issue and bypasses having to manually install.

Here's a Tidbits article on both updates, and with more explanation:

Remember, this exploit--before patching--required uninhibited physical access to your Mac (and maybe logging on an unsecured LAN).
[Opinion] Comments in the article and in the comments section below repeat the trope that you should never install an update immediately. That ignores the extreme rarity of such a mistake. And it ignores the many security enhancements built into every update. And it ignores the continuous nature of updates, any one of which could theoretically fix an older bug but introduce a new one. There's no magic sweet spot in the update timeline. So I'll stick to my advice, which mirrors Apple's: keep your Mac updated for best security.
