If you are using an iPhone, iPad Air and an 6th-gen iPod touch or any idevices that you bought for the past 4 years, probably received the update notification regarding the iOS 11.2.2 update.

Apple did not provide much information about the update aside from the usual “iOS 11.2.2 provides a security update”, however if you will look deeper on the provided link (https://support.apple.com/en-sa/ht201222) the update is to mitigate the effects of Spectre for Safari and WebKit.

Spectre vulnerability is one of the two security vulnerability (the other one is called Meltdown) that was discovered independently by Jann Horn from Google’s Project Zero and Paul Kocher.

In their release notes, Apple said;

Available for: iPhone 5s and later, iPad Air and later, and iPod touch 6th generation

Description: iOS 11.2.2 includes security improvements to Safari and WebKit to mitigate the effects of Spectre (CVE-2017-5753 and CVE-2017-5715).

We would like to acknowledge Jann Horn of Google Project Zero; and Paul Kocher in collaboration with Daniel Genkin of University of Pennsylvania and University of Maryland, Daniel Gruss of Graz University of Technology, Werner Haas of Cyberus Technology, Mike Hamburg of Rambus (Cryptography Research Division), Moritz Lipp of Graz University of Technology, Stefan Mangard of Graz University of Technology, Thomas Prescher of Cyberus Technology, Michael Schwarz of Graz University of Technology, and Yuval Yarom of University of Adelaide and Data61 for their assistance.
