Security Updates for older macOS

Mojave and High Sierra Security Update 2020-006 were made available on 12 November through Software Update. 

Their accompanying security release notes are here, and include two of the kernel vulnerabilities and the font parser bug already fixed in Catalina. 

They don’t appear to be available yet as standalone installers.

As these are essentially the same fixes already supplied in 10.15.7 Supplemental Update, there’s no matching security update for Catalina.

This is expected to be the very last security update which Apple provides for High Sierra.
