Eight New Spectre-Like Vulnerabilities Discovered on Intel CPUs

After the discovery of the Meltdown and Spectre vulnerabilities went public early this year, it is not surprising security researchers have continued to explore the speculative computing algorithms these vulnerabilities were present in for more issues. Thus far, apparently eight new vulnerabilities have been found that Intel CPUs are susceptible to, though AMD and ARM-based processors might be vulnerable as well but that research has not been done yet. They are similar enough to Spectre that they are being referred to as Spectre Next Generation, but each are distinct enough to technically deserve their own names.

Intel is aware of these new vulnerabilities and have them in its system for tracking, with four of them marked as 'high risk' with the other four at medium. At least one of these vulnerabilities is decidedly more critical than the original Spectre vulnerabilities because of its ease of use. The two original Spectre variants could be used to attack Intel, AMD, and ARM-based processors, but were difficult to exploit, somewhat lessening the risk of them. This new vulnerability though is easy to use and would give an attacked access from one virtual machine to others on the same host, and access to the host system itself. There are still other kinds of attacks that would be easier to use though, so these Spectre-NG vulnerabilities might not materialize into actual threats, but aside from them being fixed, this is not good news.

NOT GOOG NEWS at all... an easy to Implement bug that can "see" other VMs and corrupt the host with perhaps other bugs is very bad news ...What if it doing it's magic already? If AMD is immune to this then sell Intel
