New Exploit Breaks Current Spectre Defenses; Fixes Hard without Performance Impact Like by Researchers from the University of Virginia School of Engineering recently disclosed a new Spectre hardware exploit that can steal secrets via Intel/AMD micro-op caches and circumvents current Spectre defenses. Intel and AMD say no new guidance is needed. Researchers say suggested fixes are inconvenient to deploy or have performance drawbacks. Ashish Venkat, William Wulf career enhancement assistant professor of computer science at UVA Engineering, explained the exploit in layman terms: Think about a hypothetical airport security scenario where TSA lets you in without checking your boarding pass because (1) it is fast and efficient, and (2) you will be checked for your boarding pass at the gate anyway. ....
Intel, AMD Dispute Findings on Chip Vulnerabilities May 20, 2021 Compliance DougOlenick) • May 6, 2021 Get Permission Intel and AMD are disputing the findings of researchers from two universities who say they ve discovered new attacks on Intel and AMD processors that can bypass most of the defenses put in place earlier for similar Spectre and Meltdown attacks. An attacker exploiting the vulnerabilities could gain access to encryption keys, passwords and other data, the report says. Intel and AMD insist that users of their chips do not need to take any additional security measures as a result of the discovery because existing protections are adequate. ....
New Spectre Flaws in Intel and AMD CPUs Affect Billions of Computers When Spectre, a class of critical vulnerabilities impacting modern processors, was publicly revealed in January 2018, the researchers behind the discovery said, As it is not easy to fix, it will haunt us for quite some time, explaining the inspiration behind naming the speculative execution attacks. Indeed, it s been more than three years, and there is no end to Spectre in sight. A team of academics from the University of Virginia and University of California, San Diego, have discovered a new line of attack that bypasses all current Spectre protections built into the chips, potentially putting almost every system desktops, laptops, cloud servers, and smartphones once again at risk just as they were three years ago. ....
UVA Engineering Computer Scientists Discover New Vulnerability Affecting Computers Globally In 2018, industry and academic researchers revealed a potentially devastating hardware flaw that made computers and other devices worldwide vulnerable to attack. Researchers named the vulnerability Spectre because the flaw was built into modern computer processors that get their speed from a technique called “speculative execution,” in which the processor predicts instructions it might end up executing and preps by following the predicted path to pull the instructions from memory. A Spectre attack tricks the processor into executing instructions along the wrong path. Even though the processor recovers and correctly completes its task, hackers can access confidential data while the processor is heading the wrong way. ....
