New Intel Coffee Lake CPUs offer hardware-based protections against some -but not all- Spectre and Meltdown variants. Continue reading New Ninth-Gen Intel CPUs Shield Against Some Spectre, Meltdown Variants
Intel processors are vulnerable to one or more L1 data cache information disclosure and terminal fault attacks via a speculative execution side channel. These attacks are known as L1 Terminal Fault:SGX,L1 Terminal Fault:OS/SMM,and L1 Terminal Fault:VMM. Continue reading VU#982149: Intel processors are vulnerable to a speculative execution side-channel attack called L1 Terminal Fault (L1TF)
Three new Spectre-class vulnerabilities that impact how Intel chips process information were revealed on Tuesday. The bugs mean data meant to be protected can be accessed by a hackers due to speculative execution leaks, a problem that’s plagued all modern processors since the beginning of the year. The problem, which ironically lays in Intel’s security technology SGX, may allow hackers to access private data including passwords and other files. The data can be stolen across virtual machines or applications on the same device. Speculative execution works like this: All modern chips make educated assumptions — the speculation — about what will happen next in order to speed up performance — the execution. The original class of attack included the Spectre (Variants 1 and 2) and Meltdown (Variant 3) vulnerabilities, discovered by Google’s Project Zero and made public in January. Virtually all modern computer chips have even impacted. There have been […]
