Here is the main detail (2 bullets, 3 vulnerabilities):  1.) Foreshadow Foreshadow (PDF) targets a new technology originally been designed to protect select code and users' data from disclosure or modification, even if the entire system falls under attack: Intel Software Guard Extensions (SGX) — CVE-2018-3615 The new attack against SGX enclaves, which is resilient to Meltdown and Spectre attacks, may allow an unauthorized attacker to steal information residing in the L1 data cache—a protected portion of a chip's core memory that holds things like passwords and encryption keys—via side-channel analysis. 2.) Foreshadow: Next Generation (NG) The second variant (PDF) includes two vulnerabilities, which target virtualization environments being used by large cloud computing providers like Amazon and Microsoft: Operating systems and System Management Mode (SMM) — CVE-2018-3620 Virtualization software and Virtual Machine Monitors (VMM) — CVE-2018-3646 These flaws also disclose sensitive information residing in the L1 data cache, including the information stored in other virtual machines running on the same third-party cloud, with local user access or guest OS privilege via a terminal page fault and side-channel analysis.
