Apple Updates Everything. Again.
After a rushed release of iOS 11.2 over the weekend to fix a "December 2nd Crash" bug, and last weeks special update to fix the passwordless root authentication bypass in macOS, Apple today released its official set of security updates. With this, we also received details about the security issues patched in iOS this weekend. Apple's different operating systems share a lot of code with each other, and as a result, they also share some vulnerabilities. I am trying to organize the details in a table below (starting with macOS. Others will be added soon)
