Apple's Safari update protects devices from Spectre flaw

The Meltdown attack method is addressed by updates "iOS 11.2, macOS 10.13.2, and tvOS 11.2", according to Apple's announcement. iOS 11.2.2 brings further fortifications for the mobile operating system against the Spectre vulnerability, and is available right now to all supported devices (iPhone 5s and newer, iPad Air and newer).

The supplemental update to macOS High Sierra likely brings mitigations to help defend against Meltdown and Spectre, two serious security vulnerabilities that apply to all modern processors and affect almost all computing devices and operating systems.

Known as "Spectre" and "Meltdown", the issues "apply to all modern processors and affect almost all computing devices and operating systems", Apple said in a press release.

Apple has released security updates to safeguard several of its products from the recently discovered Spectre vulnerability.

On Monday, Apple announced that it also has patches to mitigate the Spectre vulnerability in iOS and macOS.

The iPhone maker had said on Thursday it will release a patch for the Safari web browser on its iPhones, iPads and Macs.

Amid releasing updates for both the Spectre and Meltdown flaws, Apple urges users not to download applications from sources outside of the App Store. "The Project Zero researcher, Jann Horn, demonstrated that malicious actors could take advantage of speculative execution to read system memory that should have been inaccessible", Google spokespersons wrote in an official blog post. The flaws were nicknamed Meltdown and Spectre.

Users with eligible devices should find the update in their phone's settings under General, then Software Update. Apple's macOS updates deal with Intel's Spectre chip flaw.

macOS High Sierra 10.13.2 is a free update for anyone who owns a compatible machine.

"Check with your operating system vendor or system manufacturer and apply any available updates as soon as they are available", the company said.
