![]() At the time of disclosure (2018), this included all devices running any but the most recent and patched versions of iOS, Linux, macOS, or Windows. Meltdown affects a wide range of systems. It allows a rogue process to read all memory, even when it is not authorized to do so. Meltdown affects Intel x86 microprocessors, IBM POWER processors, and some ARM-based microprocessors. Meltdown is one of the two original transient execution CPU vulnerabilities (the other being Spectre). Intel x86 microprocessors, IBM POWER processors, and some ARM-based microprocessors And you just can't call them back and change them," Lipp says.The logo used by the team that discovered the vulnerability "If you have an issue in hardware, it's not very easy to just change the hardware because you already sold millions of CPUs. While a software patch might mitigate the problem, it is really a hardware issue. He tells Sydell that the problem is found on millions of computers, as well as on smartphones and in cloud storage provided by companies such as Google, Amazon Web Services, Apple and Microsoft. Moritz Lipp of Austria's Graz University of Technology is one of the researchers who found the flaw. But the security flaws, which were built into the chips from Intel, Advanced Micro Devices and ARM, allow one program to spy on another." Intel said it was working to "develop an industry-wide approach to resolve issue promptly."Īs NPR's Laura Sydell reported for All Things Considered, "When you install a program on your computer, there's generally a wall between it and other programs. We wrote earlier that security researchers at Google and elsewhere discovered vulnerabilities in chips made by Intel, AMD, ARM Holdings and other companies. The mitigations and patches will probably multiply." And new variants of attacks may very well circumvent the protections companies have put together during the last few months during which the exploits were kept secret. In the coming days we plan to release mitigations in Safari to help defend against Spectre."Įven so, as Devin Coldewey reports for TechCrunch: "If you're wondering why people keep saying, 'mitigate' instead of 'fix' or 'counteract' or something, it's because Meltdown and Spectre take advantage of computing practices so basic that avoiding them is extremely difficult and complex. The company says it has "already released mitigations in iOS 11.2, macOS 10.13.2, and tvOS 11.2 to help defend against Meltdown. The good news is that "there are no known exploits impacting customers at this time" and that a change could come soon, according to Apple. In a statement, released by Apple on Thursday, the company announced, "All Mac systems and iOS devices are affected." ![]() The problems found in the chips could allow hackers to get access to passwords and other sensitive data stored on personal computers. If you thought your MacBook or iPhone would be immune to the Meltdown and Spectre microprocessor flaws acknowledged earlier this week by Intel, you would be wrong. ![]() Apple says its iOS devices are among those affected by the Meltdown vulnerability. ![]() The iOS 11 control center is displayed on the iPhone 8 Plus in New York in September. ![]()
