9 Years of AMD Processors Vulnerable to 2 New Side-Channel Attacks

9 Years of AMD Processors Vulnerable to 2 New Side-Channel Attacks
Mar 09, 2020
AMD processors from as early as 2011 to 2019 carry previously undisclosed vulnerabilities that open them to two new different side-channel attacks, according to a freshly published research. Known as " Take A Way ," the new potential attack vectors leverage the L1 data (L1D) cache way predictor in AMD's Bulldozer microarchitecture to leak sensitive data from the processors and compromise the security by recovering the secret key used during encryption. The research was published by a group of academics from the Graz University of Technology and Research Institute of Computer Science and Random Systems (IRISA), who responsibly disclosed the vulnerabilities to AMD back in August 2019. "We are aware of a new white paper that claims potential security exploits in AMD CPUs, whereby a malicious actor could manipulate a cache-related feature to potentially transmit user data in an unintended way," AMD said in an advisory posted on its website over the weekend

AMD Acknowledges Newly Disclosed Flaws In Its Processors — Patches Coming Soon

AMD Acknowledges Newly Disclosed Flaws In Its Processors — Patches Coming Soon
Mar 21, 2018
AMD has finally acknowledged 13 critical vulnerabilities, and exploitable backdoors in its Ryzen and EPYC processors disclosed earlier this month by Israel-based CTS Labs and promised to roll out firmware patches for millions of affected devices 'in the coming weeks.' According to CTS-Labs researchers, critical vulnerabilities ( RyzenFall, MasterKey, Fallout, and Chimera ) that affect AMD's Platform Security Processor (PSP) could allow attackers to access sensitive data, install persistent malware inside the chip, and gain full access to the compromised systems. Although exploiting AMD vulnerabilities require admin access, it could help attackers defeat important security features like Windows Credential Guard, TPMs, and virtualization that are responsible for preventing access to the sensitive data from even an admin or root account. In a press release published by AMD on Tuesday, the company downplays the threat by saying that, "any attacker gaining unauthorised ad

13 Critical Flaws Discovered in AMD Ryzen and EPYC Processors

13 Critical Flaws Discovered in AMD Ryzen and EPYC Processors
Mar 13, 2018
Security researchers claimed to 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. All these vulnerabilities reside 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. The alleged vulnerabilities are categorized into four classes—RYZENFALL, FALLOUT, CHIMERA, and MASTERKEY—and threaten wide-range of servers, workstations, and laptops running vulnerable AMD Ryzen, Ryzen Pro, Ryzen Mobile or EPYC processors. Discovered by a team of researchers at Israel-based CTS-Labs, newly disclosed  unpatched vulnerabilities defeat AMD's Secure Encrypted Virtualization (SEV) technology and could
