Apple releases iOS 11.2.2 security update for iPhone and iPad

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).

Overnight Apple has released the latest update to their mobile OS, with iOS 11.2.2 delivering a security update that patches the Spectre security vulnerabilities.

The other side of the recent security discovery was Meltdown which was addressed in the iOS 11.2 update.

The drive culminated in Blake Bortles' 1-yard touchdown pass to Ben Koyack with 49 seconds remaining in the quarter. Jacksonville quarterback Blake Bortles was more effective as a runner than passer.

As is typical, Apple provides few details beyond making it clear which vulnerabilities are targeted, but the firm does thank the researchers responsible for finding the bugs, including Jann Horn of Google Project Zero, in the release notes. The download is now available from the App Store under "Updates". Likewise, the macOS High Sierra 10.13.2 Supplemental Update uses similar language with regards to stamping out the Spectre threat.

iPhone and iPad users are urged to update their software immediately via the device's General Settings section.

First reported ahead of its official announcement as an Intel exclusive flaw, the security issues hitting nearly every modern computer were later revealed as three variants of two core vulnerabilities: The cross-vendor vulnerabilities Variant 1 and Variant 2, together known as Spectre, and the Intel-specific Variant 3, known as Meltdown. Apple claims the Metldown vulnerability was addressed in iOS 11.2, and since there isn't a hardware fix for Spectre, the company issued this over-the-air update to all compatible devices. iOS 11.2.2 is available for iPhone 5s and later, iPad Air and later, and iPod touch 6th generation. There are reports the Microsoft fix (Security Update for Windows KB4056892) bricks some AMD systems.
