To initiate a Spectre- or Meltdown-based attack, the attacker must be able to run code on the victim's processor. There were also updates for Safari 11.0.2 for macOS 10.12 Sierra and OS X 10.11 El Capitan.įollowing the updates, WebKit, the open-source engine behind Safari, has shared what Meltdown and Spectre mean for its technology stack. These add the first in what may be a series of updates to help protect the Safari web browser from Spectre-based attacks.Īvailable for: iPhone 5s and later, iPad Air and later, and iPod touch 6th generationDescription: iOS 11.2.2 includes security improvements to Safari and WebKit to mitigate the effects of Spectre (CVE-2017-5753 and CVE-2017-5715).Īvailable for: macOS High Sierra 10.13.2Description: 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). January 8, 2018:Īpple today pushed out iOS 11.2.2 for iOS and a supplemental update to macOS 10.13.2. It's natural for people to be confused and unfortunately typical for publishers to rush for headlines.īut we owe it to ourselves and our audiences, be they social or traditional, to take a breath, take our time, and get this stuff right. Meltdown and Spectre are some the biggest issues the industry has ever faced. What happened? John Poole, the developer of the Geekbench benchmark tool, has the answer: So, the affects of any Spectre mitigations wouldn't manifest in direct CPU benchmarks at all. IOS 11.2.2 includes security improvements to Safari and WebKit to mitigate the effects of Spectre (CVE-2017-5753 and CVE-2017-5715). Which should have set off alarm bells for anyone covering the story because iOS 11.2.2 patches Spectre not at the OS level but at the browser level. And the blame for the slowdown was placed squarely on iOS 11.2.2's Spectre mitigation. It was based on a set of comparative CPU benchmarks for an iPhone before and after the iOS 11.2.2, posted to the internet, that appeared to show significant addition slowdown post-update. Sigh.Ī strange story began gaining traction over the weekend. January 15, 2018: No, iOS 11.2.2's Spectre patch isn't crippling older iPhones. I will keep you updated as we learn more and thank you for your patience. I assure you we are working around the clock to ensure we are addressing these issues. The security of our products is critical for Intel, our customers and partners, and for me, personally. I apologize for any disruption this change in guidance may cause.
