Sumup: CPU hardware vulnerable to side-channel attacks (Meltdown, Spectre and more)

If you’re confused by the avalanche of early reports, denials, and conflicting statements about the massive security issues announced in the last days, don’t worry — you’re far from the only one. Here’s what you need to know about Meltdown and Spectre, the two huge bugs that affect practically every computer and device out there. Source of the article: Kernel panic! What are Meltdown and Spectre, the bugs affecting nearly every computer and device?   What are these flaws? Short answer: Bugs at a fundamental level that allow critical information stored deep inside computer systems to be exposed.       Meltdown Meltdown breaks the most fundamental isolation between user applications and the operating system. This attack allows a program to access the memory, and thus also the secrets, of other programs and the operating system. If your computer has a vulnerable processor and runs an unpatched operating system, it is not safe to work with sensitive information without the chance of leaking the information. This applies both to personal computers as well as cloud infrastructure. Luckily, there are software patches against Meltdown.  Meltdown Paper Spectre Spectre breaks the isolation between different applications. It allows an attacker to trick error-free programs, which…
