![]() ![]() Graham said fixing the problem will require a major redesign of processors and operating systems, but that's not something most consumers will notice. "If you aren't up to date, then there's a lot of other nasties out there you should probably also be worrying about." Critical 'Meltdown' and 'Spectre' Flaws Break Basic Security for Intel, AMD, ARM Computers WIRED Andy Greenberg Security 3:00 PM A Critical Intel Flaw Breaks Basic. A newly-discovered Downfall vulnerability found in Intel chips may affect older Macs powered by these processors. "If you download the latest update from Microsoft, Apple, or Linux, then the problem is fixed for you and you don't have to worry," security researcher Rob Graham said in a blog post Thursday. Google says Android devices are protected if they have the latest security updates. Mozilla says it's also implementing a short-term mitigation that disables some capabilities of its Firefox browser. Meltdown affects only Intel products, but Spectre is a problem in processors made by Intel, AMD, and ARM (whose chips are typically found on mobile devices, including both iOS and Android. ![]() In cybersecurity circles, this has been the year of Spectre and Meltdown. There are already Meltdown patches for Microsoft's Windows, Apple's macOS and Linux. In the spirit of Meltdown and Spectre, a new vulnerability called Foreshadow could expose Intel's secure enclave to attack. The federal organization said "fully removing the vulnerability" requires replacing the hardware already embedded in millions of computing devices.Īpple pointed out that "exploiting many of these issues requires a malicious app to be loaded on your Mac or iOS device," so it suggested consumers could protect themselves by "downloading software only from trusted sources such as the App Store."Ĭonsumers can mitigate the underlying vulnerability by making sure they patch up their operating systems with the latest software upgrades. Microsoft says it began investigating SSB in November, after Spectre and Meltdown were already being researched, but before the flaws were publicly disclosed in January. Advice from the U.S Computer Emergency Readiness Team's was grim.
