Researchers reveal Meltdown and Spectre CPU exploits
by from Techreport on (#3CBGX)
After building speculation fueled by media reports (including our own) ahead of a planned coordinated release, researchers at Google, academic institutions, and other companies have revealed a pair of attack classes this afternoon that exploit fundamental operating principles of modern CPUs to allow attackers to arbitrarily read data from the memory of vulnerable systems.
The first, called "Meltdown," breaks down CPU-level protections that prevent unprivileged applications from reading arbitrary system memory, including privileged memory locations corresponding ...
