AMD will issue Spectre fixes of its own starting this week

In other developments, Microsoft also warned that some computers powered by older processors probably won't work as well as they once did after the antidotes to Spectre and Meltdown are installed. As a part of that vigilance, I wanted to update the community on our actions to address the situation. However, security researchers discovered that it was possible for malicious software to access protected memory areas and read data potentially including passwords and encryption keys.

Intel said that systems equipped with its latest 8th generation (including the Kaby Lake, Coffee Lake chips) will be see the smallest effect, with the expected impact being less than six per cent. Papermaster said, "We are working closely with them to correct an issue that paused the distribution of patches for some older AMD processors (AMD Ultra families) earlier this week". These threats seek to circumvent the microprocessor architecture controls that preserve secure data.

Intel has admitted that a recent patch rolled out to address massive CPU security flaws is causing reboot problems for some of its customers.

The Meltdown and Spectre CPU flaws have dominated the technology world over the past two weeks.

But, if you're wondering just how much slower will your PC become after Meltdown and Spectre patches, we are here with the answers. "We have defined additional steps through a combination of processor microcode updates and OS patches that we will make available to AMD customers and partners to further mitigate the threat".

Intel posted a statement on its website saying, "We have received reports from a few customers of higher system reboots after applying firmware updates".

"The Meltdown and Spectre vulnerabilities require adjustment to critical, low-level interfaces in affected operating systems", said Mark Nunnikhoven, vice president of cloud security at Trend Micro. He has written for Reuters, Bloomberg, Crain's New York Business and The New York Times. Sadly, the company has been forced to confirm a flaw in the fix for the flaw which is causing systems based on the company's older Haswell and Broadwell microarchitectures to randomly reboot.

All told, AMD is approaching the problem with a mix of OS patches and microcode updates. This particular bug allows for 'Branch Target Injection' and is applicable to AMD processors. However, you understand and agree that at the time of any transaction that you make, one or more contributors may have a position in the securities written about.

AMD will begin issuing optional updates to guard against Spectre vulnerabilities later this week, the company said in a new blog post.
