Intel CPUs impacted by new Zombieload side-channel attack

They're calling it Zombieload.


Quote:
Academics have discovered a new class of vulnerabilities in Intel processors that can allow attackers to retrieve data being processed inside a CPU.

The leading attack in this new vulnerability class is a security flaw named Zombieload, which is another side-channel attack in the same category as Meltdown, Spectre, and Foreshadow.

New attack on speculative execution

Just like the first three, Zombieload is exploited by taking advantage of the speculative execution process, which is an optimization technique that Intel added to its CPUs to improve data processing speeds and performance.

The good news

But things aren't as bleak as they were when Meltdown and Spectre were first disclosed in January 2018. For starters, Intel hasn't been caught with its pants down like the last time, and the company has already shipped microcode updates.

Furthermore, newer processors aren't impacted, as they already include protections against speculative execution attacks --such as the MDS attacks-- since last year when Meltdown and Spectre first hit, and Intel modified the way its CPU's worked.

In addition, Microsoft, Apple, and the Linux project are expected to have operating system updates roll out later today, or in the coming days.
