Since the disclosure of Spectre and Meltdown in January 2018, much research had been done on vulnerabilities related to speculative execution. On 3 May 2018, eight additional Spectre-class flaws provisionally named Spectre-NG by c't (a German computer magazine) were reported affecting Intel and possibly AMD and ARM processors. Intel reported ...
Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...
The Meltdown and Spectre CPU vulnerabilities hung like a shadow over the festivities of CES. What's typically a celebration of consumer electronics was instead a stark reminder of just how far ...
The vulnerabilities were dubbed Spectre and Meltdown , and provided malicious actors with avenues to access sensitive data -- such as usernames and passwords -- even if stored in protected memory ...
Speculative execution exploit Variant 4, [8] is referred to as Speculative Store Bypass (SSB), [1] [9] and has been assigned CVE-2018-3639. [7] SSB is named Variant 4, but it is the fifth variant in the Spectre-Meltdown class of vulnerabilities.
In 2018, following the discovery of the Spectre and Meltdown vulnerabilities to the public, Google accelerated the work, culminating in a 2019 release of the feature. In 2021, Firefox also launched their own version of site isolation which they had been working on under the codename Project Fission .
In 2017, two CPU vulnerabilities (dubbed Meltdown and Spectre) were discovered, which can use a cache-based side channel to allow an attacker to leak memory contents of other processes and the operating system itself. A timing attack watches data movement into and out of the CPU or memory on the hardware running the cryptosystem or algorithm ...
According to one expert, "[Foreshadow] lets malicious software break into secure areas that even the Spectre and Meltdown flaws couldn't crack". [16] Nonetheless, one of the variants of Foreshadow goes beyond Intel chips with SGX technology, and affects "all [Intel] Core processors built over the last seven years". [3]
