In January 2018, security news media was abuzz over a new class of vulnerability called side channel vulnerabilities. Spectre, Meltdown and Foreshadow are some of the best known. They exploit weaknesses in speculative execution in microprocessors to leak unauthorized information. Side channel vulnerabilities allow attackers to bypass account permissions, virtualization boundaries and protected memory regions. […]
