Apple releases iOS and macOS updates with a mitigation for Spectre CPU flaw

“Apple just released iOS 11.2.2 with some Safari and WebKit improvements to mitigate the Spectre vulnerability,” Romain Dillet reports for TechCrunch. “macOS is also receiving an update. It’s a supplemental update to macOS High Sierra 10.13.2 and it includes the same fix.”

“As always, you should update your devices with the latest security patches. In this case, Meltdown and Spectre are serious vulnerabilities,” Dillet reports. “Meltdown was already addressed in previous updates. iOS 11.2, macOS 10.13.2 and tvOS 11.2 already included mitigations for Meltdown. Apple Watch chips aren’t affected by Meltdown.”

“Spectre isn’t as serious as it only breaks the isolation between multiple applications,” Dillet reports. “But it can be exploited using Javascript in a web browser.”

Now we wait to see how much performance negatively impacted by these software bandaids via research from independent parties.

  1. Great job Apple, you scared people from wanting to upgrade their iOS device. What are you going to slow down with this update? The camera?

    1. I’m running 3 security cameras on one monitor and surf the internet on another monitor connected to a Late 12 MacMini quad i7 16GB ram and I can’t detect any slowing after the update so far.

  2. does not seem any slower to me!
    Model Name: iMac
    Model Identifier: iMac18,3
    Processor Name: Intel Core i5
    Processor Speed: 3.8 GHz
    Number of Processors: 1
    Total Number of Cores: 4
    L2 Cache (per Core): 256 KB
    L3 Cache: 6 MB
    Memory: 24 GB

  3. Well, yes and no.

    Yes, it is vulnerable to any exploits that may be developed in the future (there is no malware in the wild yet).

    No, it will not become vulnerable unless somebody who can program at the machine instruction level devotes a considerable amount of effort writing malware, knowing full well that it won’t work on any newer device, and you then download it to your Mac.

    1. Twelve years? I do not agree at all. Apple did not create this problem and, even if Apple were responsible, it does not make any sense to waste resources delivering updates for dead OS versions running on obsolete hardware.

      And I state this with the understanding that I have a 2007 iMac and a 2008 iMac – roughly a decade old. I do not expect Apple to develop and distribute security updates for those old systems. A cut-off of five years would seem more reasonable, and I would think that the vast majority of those computers and devices could run the latest version of macOS/iOS with the security mitigations already being deployed. For those with software incompatibilities, perhaps Apple could reach back a couple of versions in macOS to help out.

      1. 5 years is absolutely NOT acceptable for an Apple product, particularly a Mac. I think that a very large proportion of Macs are in use 8-10 years, and that is part of the reason people are willing to pay a premium for them.

  4. I attempted to install this update and my 2010 27″ iMac is now apparently bricked. The screen powers up with thin green and orange vertical lines, the fan either screams or doesn’t run at all with each attempted reboot. I’ve tried to option-reboot to start from a bootable thumb drive, but no luck. It’s a bit of a heartbreak, honestly.

    1. So you did the update? and your computer is slow now? what year and model, I’m holding off on this update I have an older MBP 2010 don’t want to fuck it up.

  5. Definitely some effect on my 7 Plus. Normal usage is fine but I have noticed that some game animations aren’t quite as smooth. They’re not bad, just not as silky smooth as before.
    Will be interesting to see if any developers change their apps to cater for the iOS patches.
