'Leakage ... is visible in all Intel generations starting from first-gen Core CPUs'
Updated Further demonstrating the computational risks of looking into the future, boffins have found another way to abuse speculative execution in Intel CPUs to steal secrets and other data from running applications.
This security shortcoming can be potentially exploited by malicious JavaScript within a web browser tab, or malware running on a system, or rogue logged-in users, to extract passwords, keys, and other data from memory. An attacker therefore requires some kind of foothold in your machine in order to pull this off. The vulnerability, it appears, cannot be easily fixed or mitigated without significant redesign work at the silicon level. ...Click Here
