Supplemental edition of Safari 11.1 eliminates two WebKit-related memory corruption vulnerabilities. (Free)
For High Sierra (10.13), you seem to get this Safari update along with Security Update 2018-001.
This wasn’t exactly a surprise, but I didn’t see it mentioned in the article (for which I am all the same grateful, as always).
Good note — you’re absolutely right.
It seems odd that Apple would release this update without even changing the normal version number.
It has to do with future updates. I won’t pretend to understand it all, but know it’s done to prevent confusion for users that failed to run the security update for some reason when macOS 10.13.5 or Safari 11.11.1 or whatever is already in the pipeline is released.
Yeah, I assume as much too. But it feels like a failure of a versioning policy to end up in a situation where this sort of thing happens.
