CVE-2018-3640

In January 2018, the entire computer industry was put on alert by two new processor vulnerabilities dubbed Meltdown and Spectre that defeated the fundamental OS security boundaries separating kernel and user space memory. The flaws stemmed from a performance feature of modern CPUs known as speculative execution and mitigating them required one of the biggest patch coordination […]

In January 2018, security news media was abuzz over a new class of vulnerability called side channel vulnerabilities. Spectre, Meltdown and Foreshadow are some of the best known. They exploit weaknesses in speculative execution in microprocessors to leak unauthorized information. Side channel vulnerabilities allow attackers to bypass account permissions, virtualization boundaries and protected memory regions. […]

Microsoft this week made available another round of microcode updates created by Intel for mitigating the recently disclosed speculative execution vulnerabilities tracked as Foreshadow and L1 Terminal Fault (L1TF) .

On May 21, 2018, Google Project Zero (GPZ), Microsoft and Intel disclosed two new Spectre- and Meltdown-related chip vulnerabilities: Speculative Store Bypass (SSB) and Rogue System Registry Read. The customer risk from both disclosures is low. Then on June 13, 2018, Intel released a security advisory on the Lazy FP State Restore vulnerability, CVE-2018-3665, involving […]

Last week Oracle started releasing software and microcode updates for products affected by the recently disclosed variants of the Spectre and Meltdown flaws. In May, tech giants Intel, AMD, ARM, IBM, Microsoft and other tech firms teamed to disclose two new variants of both Meltdown and Spectre issues. The so-called Variant 4 (CVE-2018-3639) relies on a Speculative Store Bypass (SSB), […]

Oracle announced on Friday that it has started releasing software and microcode updates for products affected by the recently disclosed variants of the Spectre and Meltdown vulnerabilities.

A new flaw that can allow an attacker to obtain access to sensitive information on affected systems has been discovered in modern CPUs. CVE-2018-3639, discovered by independently by Google Project Zero and Microsoft Security Response Center researchers and dubbed “Variant 4,” is a Speculative Store Bypass (SSB) vulnerability, and is considered to be a new variant of the previously revealed Spectre Variant 1 vulnerability. “Variant 4 is a vulnerability that exploits ‘speculative bypass.’ When exploited, … More →

Intel, AMD, ARM, IBM, Microsoft and other major tech companies on Monday released updates, mitigations and advisories for two new variants of the speculative execution attack methods known as Meltdown and Spectre.
