Security Alert: Processors Meltdown!

Hello,

Recently multiple disclosed security vulnerabilities took the Internet by storm. Dubbed "Meldown" and "Spectre", those vulnerabilities seem to affect numerous systems and processors including Intel, AMD, ARM; thus it has the potential to affect PCs, servers, networking equipment, mobile devices and even cloud.
An attacker can exploit those vulnerabilities by running a special code locally on the system which could result in accessing privileged data of another process through unprivileged access level.

Meltdown: Rogue data cache load (CVE-2017-5754)
Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis of the data cache.

Spectre Variant 1: Bounds checking bypass (CVE-2017-5753)
Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.

Spectre Variant 2: Branch target injection (CVE-2017-5715)
Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. Link
