Earlier today, Apple released a security update for iOS 11, which was meant to mitigate the effects of the recently-discovered Spectre vulnerability.
And now the same fix is rolling out to Macs, as Apple has officially released macOS High Sierra 10.13.2, which primarily focuses on patching the Spectre vulnerability, effectively aiming to mitigate any issues tied to it. The new software is available as a standard software update for compatible iMacs and MacBooks, and can be downloaded and installed from the Mac App Store right now.
“macOS High Sierra 10.13.2 Supplemental Update includes security improvements to Safari and WebKit to mitigate the effects of Spectre (CVE-2017-5753 and CVE-2017-5715).”
Both Spectre and Meltdown are serious security issues that are tied to the hardware, rather than software-based exploits. They were both discovered recently and gained plenty of attention. It was discovered that Apple had already addressed some issues, but it recently confirmed that all of its devices were affected by both Spectre and Meltdown.
It also confirmed at the time that subsequent software updates would aim to address those issues and patch the holes. These new software updates for iOS and macOS High Sierra should limit a user’s vulnerabilities through Spectre and Meltdown.
The new software is available now, and it should be downloaded and installed at your earliest convenience.
It’s good to see Apple getting these software updates out as quickly as possible. Considering there are no hardware fixes available to address Spectre, these software updates are all users can expect at this point. Which is certainly better than nothing, considering how widespread Spectre and Meltdown are.
