Threat Brief: Meltdown and Spectre Vulnerabilities
Summary: On January 3, 2018, researchers including Google Project Zero disclosed three processor vulnerabilities grouped as Spectre (CVE-2017-5753 and CVE-2017-5715) and Meltdown (CVE-2017-5754), affecting Intel and ARM chips with AMD's status unclear. The flaws are hardware-based information disclosure issues that let user-mode applications read privileged kernel data, and Unit 42 reported no known active attacks at the time of writing.
Bottom line: Because the flaws sit in the processor itself, only replacement or firmware updates fully address them, and older systems like Windows XP and older Android and IoT devices will likely never receive fixes - so the exposure is nearly every device with a modern processor, with shared-hosting environments the greatest area of risk.
