On 21 May 2024, Intel published information on the first two Spectre-NG class side-channel vulnerabilities CVE-2024-3640 (Rogue System Register Read, Variant 3a) and CVE-2024-3639 (Speculative Store Bypass, Variant 4), also referred to as Intel SA-00115 and HP PSR-2024-0074, respectively. Se mer Spectre refers to one of the two original transient execution CPU vulnerabilities (the other being Meltdown), which involve microarchitectural timing side-channel attacks. These affect modern microprocessors that … Se mer In 2002 and 2003, Yukiyasu Tsunoo and colleagues from NEC showed how to attack MISTY and DES symmetric key ciphers, respectively. In 2005, Daniel Bernstein from the University of Illinois, Chicago reported an extraction of an OpenSSL AES key via a cache timing attack, and Se mer Since Spectre represents a whole class of attacks, most likely, there cannot be a single patch for it. While work is already being done to address special cases of the vulnerability, the original website devoted to Spectre and Meltdown states: "As [Spectre] is not easy … Se mer • Row hammer • SPOILER (security vulnerability) Se mer Spectre is a vulnerability that tricks a program into accessing arbitrary locations in the program's memory space. An attacker may read the content of accessed memory, and thus … Se mer As of 2024, almost every computer system is affected by Spectre, including desktops, laptops, and mobile devices.

Linux kernel developers have referred to this measure as kernel page-table isolation (KPTI). KPTI patches have been developed for Linux kernel 4.15, and have been released as a backport in kernels 4.14.11, 4.9.75. Red Hat released kernel updates to their Red Hat Enterprise Linux distributions version 6 and version 7. C… Nettet16. nov. 2024 · Save the file with CTRL+S, and exit the editor with CTRL+X.
