Reading Time: 2 minutesNow that Meltdown and Spectre vulnerabilities are almost fixed, there is a new critical vulnerability for several Intel CPU called BranchScope, discovered by some researchers from four universities. It’s again a speculative execution issue, in the method a processor uses to predict where its current computational task. By exploiting this flaw, attackers with local access could pull data stored from memory that’s otherwise inaccessible to all applications and users.
Reading Time: 2 minutesVMware has acquired the technology and team of E8 Security. With this acquisition, VMware is further reinforcing its commitment to deliver the industry’s first intelligence-driven digital workspace to empower the employee experience and drive predictive security. Adding E8 Security’s capabilities to VMware’s digital workspace platform, VMware Workspace ONE, will enable customers to get a single platform approach that simplifies management and security by correlating data to accurately detect and respond to advanced threats using analytics.
Reading Time: 2 minutesNow that Meltdown and Spectre vulnerabilities are almost fixed, there is a new critical vulnerabilities, this time specific only for several AMD CPU. There are 13 critical security vulnerabilities and manufacturer backdoors discovered throughout AMD Ryzen & EPYC product lines. Yes, also the lates AMD CPU models! Like with Meltdown and Spectre, there is a dedicated web site (amdflaws.com) that provide more detail about them.
Reading Time: 3 minutesVMware has released (on Feb, 15th) a new vCSA version: vCenter Server 6.5 U1f, with build number 7801515. This release patches the vCSA operating system (Photon OS) mainly against two vulnerabilities: bounds-check bypass (Spectre-1, CVE-2017-5753) and rogue data cache load issues (Meltdown, CVE-2017-5754). As of now, there is still no patch for branch target injection vulnerability (Spectre-2, CVE-2017-5715). VMware has also updated the security advisory dealing with all of its virtual appliances updates for Spectre and Meltdown vulnerabilities, VMSA-2018-0007. But note that VMSA-2018-0004.2 has not been updated yet, and it still report that the suggested version for […]
Reading Time: 2 minutesWe are still far from a solution for the Meltdown and Spectre, considering the delay of the microcode releases and the complexity of the possible Spectre fixes… And now, some security researchers from NVIDIA and Princeton have discovered new variants of the Meltdown and Spectre flaws that may be more difficult to be fixed (but also to be exploited) than the originals.
Reading Time: 6 minutesThe mitigations for Meltdown and Spectre issues have involved a combination of different type of fixes: some software based, such as Microsoft and Linux versions of the “kernel page table isolation” protection, but also fome hardware based, like the Intel’s microcode updates (part that is still missing in most cases). Both type of patches can cause performance overheads and have some kind of impact on your environment. But how can you estimate it (before apply the patches) and how can you measure it (when the patches have been applied)?
Reading Time: 8 minutesIn June 2017, a team constituted of independent researchers, university research labs, and some of Google’s Project Zero members and cyberus technology discovered two security vulnerabilities enabled by the widespread use of speculative execution in most of the CPU. The problem was also independently discovered by other researchers, at about the same time. These vulnerabilities, called Meltdown and Spectre, were made public in January 2018. Meltdown and Spectre are critical vulnerabilities existing in several modern CPU: these hardware bugs allow programs to steal data which is currently processed on the computer. Meltdown and Spectre can affect personal […]
