Security researchers have discovered 13 critical Spectre/Meltdown-like vulnerabilities throughout AMD’s Ryzen and EPYC lines of processors that could allow attackers to access sensitive data, install persistent malware inside the chip, and gain full access to the compromised systems.Īll these vulnerabilities lie in the secure part of the AMD’s Zen architecture processors and chipsets-typically where device stores sensitive information such as passwords and encryption keys and makes sure nothing malicious is running when you start your PC. As per normal and responsible reporting policies, the teams of researchers that discovered the attacks are not releasing details until processor vendors are given a reasonable amount of time to develop patches, which should help ward off exploits, at least for now. Much like the first round of Spectre vulnerabilities, these newly discovered vulnerabilities rely upon a side-channel attack on a processors’ speculative execution engine. As a best practice, we continue to encourage everyone to keep their systems up-to-date. We believe strongly in the value of coordinated disclosure and will share additional details on any potential issues as we finalize mitigations. We routinely work closely with customers, partners, other chipmakers and researchers to understand and mitigate any issues that are identified, and part of this process involves reserving blocks of CVE numbers. Protecting our customers’ data and ensuring the security of our products are critical priorities for us. We reached out to Intel for comment, and the company provided this statement, which neither confirms nor denies the vulnerabilities: The vulnerabilities purportedly affect Intel and ARM processors, but the impact on AMD processors remain unknown. The online German computer magazine is reporting that eight new Spectre-class vulnerabilities have been discovered. There are now four (published) variants of the Spectre vulnerability that can be used to read memory in processors that is not intended for that application, and thus can be abused. So with your latest Chrome, you should be fine and thus safe. However, Microsoft Edge, Chrome and other major browsers have taken steps to increase the difficulty of successfully creating a side channel. In the case of Just-in-Time (JIT) compilers, such as JavaScript JIT employed by modern web browsers, it may be possible for an attacker to supply JavaScript that produces native code that could give rise to an instance of speculative Store Bypass (SSB). Vulnerable code patterns in the operating system (OS) or in applications could allow an attacker to exploit this vulnerability. An attacker who has successfully exploited this vulnerability may be able to read privileged data across trust boundaries. Variant 4 uses speculative execution, a feature common to most modern processor architectures, to potentially expose certain kinds of data through a side channel. A new subclass of speculative execution side channel vulnerabilities known as Speculative Store Bypass (SSB) has been announced and assigned CVE-2018-3639. Researchers from Microsoft and Googles Project Zero now published information about one of the vulnerabilities, the so-called fourth variant Spectre vulnerability, which can cause security issues. Today the Store Bypass (SSB) vulnerability has been published and effects Intel, AMD and ARM. Earlier on it was reported that there are eight new vulnerabilities, grouped and named as Spectre-ng, of which four are critical. They are a STEAL compared to everything else out there right now.As discussed a few weeks ago, a new Spectre vulnerability has been shared and made public today. Granted, I've only had them on for 3 hours. Unless you are extremely picky or require super accurate color reproduction - these are great. I have Dell displays at work (two) that are very similar size and specs - they are available here on Amazon for around $300 each. No input lag that I can see - these are decently fast displays. These are only 60Hz - maybe that's an issue for you, it's not for me.įallout 4 looks great in 4K. HDMI 2.0 cables included in the box - a very decent Phillips head screw driver is included in each box as well. They are being driven through an AMD RX580 8GB from MSI. I purchased two of these at once for less than two hundred dollars each. Sceptre has put the the other manufacturers on notice with these displays.
