New secret-spilling flaw affects almost every Intel chip since 2011

Security researchers have found a new class of vulnerabilities in Intel chips which, if exploited, can be used to steal sensitive information directly from the processor., The bugs are reminiscent of Meltdown and Spectre, which exploited a weakness in speculative execution, an important part of how modern processors work. Speculative execution helps processors predict to […]

Last march of the Penryns: Intel cuts Spectre fixes for some older chips

As part of its ongoing efforts to patch its systems against the Meltdown and Spectre chip flaws, Intel indicated last month that it would be issuing fixes as far back as 2005’s Yorkfield processors. But in a new guidance document the company announces that many of these older platforms will not receive fixes after all. […]

Intel announces hardware fixes for Spectre and Meltdown on upcoming chips

When the Spectre and Meltdown bugs hit, it became clear that they wouldn’t be fixed with a few quick patches — the problem runs deeper than that. Fortunately, Intel has had plenty of time to work on it, and new chips coming out later this year will include improvements at the hardware/architecture level that protect […]

Intel ships update for newest Spectre-affected chips

Intel has announced that the fix is out for its latest chips affected by Spectre, the memory-leakage flaw affecting practically all computing hardware. The patch is for the Skylake generation (late 2015) and newer, though most users will still have to wait for the code to be implemented by whoever manufactured their computer (specifically, their […]

Apple issues Meltdown fix for Macs running Sierra and El Capitan

A wise person once said, “don’t upgrade to the latest OS X until it’s been patched a few times. And even then, sometimes it isn’t really worth it, though maybe for security stuff.” These words (from before the name change to macOS) have inspired many to stay on older versions of the OS, though lately […]

Linus Torvalds declares Intel fix for Meltdown/Spectre ‘COMPLETE AND UTTER GARBAGE’

The always outspoken Linus Torvalds, best known for his continuing work on the innermost code of Linux systems, has harsh words to say and accusations to level against Intel. His evaluation of Intel’s latest proposed fix for the Meltdown/Spectre issue: “the patches are COMPLETE AND UTTER GARBAGE.” As a potential line of inquiry, he suggests: […]

Intel details performance hit for Meltdown fix on affected processors

Now that the Meltdown and Spectre cats are out of the bag and patches are being issued left and right, the main question people have is: will this affect my everyday work? Intel’s latest performance metrics suggest that yes it might, but not too much — more so if, like me, you have an older […]

Apple releases iOS and macOS updates with a mitigation for Spectre

Apple just released iOS 11.2.2 with some Safari and WebKit improvements to mitigate the Spectre vulnerability. 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 […]

Apple says Meltdown and Spectre flaws affect ‘all Mac systems and iOS devices,’ but not for long

Apple isn’t immune to Meltdown and Spectre, the major bugs in basic computing architecture that were announced yesterday to widespread amazement and horror. In an announcement, the company said that “all Mac systems and iOS devices are affected,” which sounds right, but that mitigations are either already in place or on the way. If you’re […]

Kernel panic! What are Meltdown and Spectre, the bugs affecting nearly every computer and device?

If you’re confused by the avalanche of early reports, denials, and conflicting statements about the massive security issues announced today, don’t worry — you’re far from the only one. Here’s what you need to know about Meltdown and Spectre, the two huge bugs that affect practically every computer and device out there. What are these […]
