Changes in WebAssembly Could Render Meltdown and Spectre Browser Patches Useless (bleepingcomputer.com)
Catalin Cimpanu, reporting for BleepingComputer: Upcoming additions to the WebAssembly standard may render useless some of the mitigations put up at the browser level against Meltdown and Spectre attacks, according to John Bergbom, a security researcher at Forcepoint. WebAssembly (WA or Wasm) is a new technology that shipped last year and is currently supported within all major browsers, such as Chrome, Edge, Firefox, and Safari.
The technology is a compact binary language that a browser will convert into machine code and run it directly on the CPU. Browser makers created WebAssembly to improve the speed of delivery and performance of JavaScript code, but as a side effect, they also created a way for developers to port code from other high-level languages (such as C, C++, and others) into Wasm, and then run it inside a browser. All in all, the WebAssembly standard is viewed as a success in the web dev community, and there've been praises for it all around.

The fact so many webdevs see active x, but harder to control as a success just proves the entire node.js loving lot of them have no fucking clue what they are doing and shouldn't be allowed near a computer.

Idiots.
