Meltdown Spectre chip level flaw Intel says it is rapidly issuing updates for all computers servers powered by its processors

So far no data breaches have been reported.

"It's a big one and it's a severe one".

Cloud services often share machines among many customers - and it is uncommon for, say, a single server to be dedicated to a single customer.

Spectre potentially has a wider reach.

And the Intel news continues to trickle out regarding its latest processor-gate crisis.

First, let's not panic.

In research papers made public online Wednesday, this second group of researchers identified a potential cyberattack that could exploit these vulnerabilities.

Security tools and protocols are intended to separate individual customers' data, but the recently discovered chip flaws would allow hackers to circumvent these protections. However, server side chips and most PC's in the world are facing security risks. Krzanich executed more than 644,143 in option shares at between $13 and $26 a share, then immediately sold them at more than $44 a share, according to the SEC filing.

Meanwhile, the company also deployed Kernel Page Table Isolation (KPTI) to counter the third variant known as Meltdown by "better protecting sensitive information in memory from other software running on a machine".

How does this affect my computer? . The assumption here is that further updates may be needed, and that things will only improve over time. More are on the way. That feature has been used in almost every Intel processor since 1995, and is used by many AMD and ARM processors today.

Krzanick's stock sale resulted in a $24m windfall for the CEO.

Amid complaints the patch is negatively affecting performance The firm reiterated its earlier claim that average users won't see significant downturns in output. Indeed, CERT/CC regularly consults with the Department of Defense, Department of Homeland Security, and the FBI on cybersecurity issues. Chrome web browser users are expected to receive a patch on 23 January. While it's unlikely there would be full files stored there, it's very possible it would find bits and pieces of valuable data, like SSH keys, security tokens and even passwords, ' said Mike Buckbee, Security Engineer at Varonis. Some say performance speeds of Intel computers with older processors could slow down by as much as 30 per cent, though newer Skylake processors might not have face a severe impact.

While there have been concerns that patching the flaw could hit performance by a double-digit percentage, Linus Torvalds told ZDNet it will depend on workload.

Ybarra wanted to reassure owners of the Redmond house platforms by explaining how the architecture of Xbox One is designed precisely to prevent flaws of this type that can cause damage of any kind to the console, so the owners of Xbox will not have to face problems due to Specter and Meltdown bugs.
