While CERT/CC has withdrawn its recommendation to replace processors, US-CERT - a related group that operates officially under the auspices of the Department of Homeland Security - has yet to update its own bulletin, issued earlier on Thursday. The threat and the response to the three variants differ by microprocessor company, andAMD is not susceptible to all three variants.
Meltdown, Spectre chip level flaw:Intel says it is rapidly issuing updates for all computers, servers powered by its processors. The major concern going around was that in order to fix this, OS makers would have to change how Windows, macOSandLinux manage the kernel, which would lead to a performance reduction. Intel believes these exploits do not have the potential to corrupt, modify or delete data. "I think it will affect the way that processors are designed". The vast majority of the world's cloud computing happens on Intel chips, including data centres run by Google, MicrosoftandAmazon. AndIntelsaid the flaws would have no material impact on the company's business or technology.
To improve performance, most processors try to guess what the computer program is going to do in the future. While this may seem to be the case for Meltdown, Spectre is a more widespread and deep-rooted flaw and there is no fix for it as of now.
"Intel will continue to work with its partners and others to address these issues, andIntel appreciates their support and assistance", the release added.
This time, though, Chipzilla and its chums claim to have made significant progress in deploying updates as both software patches andfirmware updates. The company already faces multiple lawsuits, including one filed Thursday by Portland lawyer Michael Fuller.
Make sure your device is up-to-date and officially supported.
Microsoft, AppleandGoogle have addressed the critical security bug with the December or January Update. With that in mind, we can probably expect a few more updates on this going forward.
"You can never reduce risk down to zero, you can only mitigate it and there are trade-offs", he added.
Intel has bore the brunt of the initial fallout because at first it was reported that only its chips were affected.
Will the patch for Meltdown and Spectre slowdown my device?
"We used our VM Live Migration technology to perform the updates with no user impact, no forced maintenance windowsand no required restarts", wrote Ben Treynor Sloss, Google Engineering Vice President, in a blog post.
