    All Intel CPUs afflicted with simple data-spewing spec-exec vulnerability

    This problem keeps looking worse for Intel, makes me happy that I chose AMD for my latest build.

    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.
    The researchers also examined Arm and AMD processor cores, but found they did not exhibit similar behavior.

    Ouch. Revives memories of the 90s 'Pentium flaw', which in fairness was more a PR problem than a widespread computation problem if I recall correctly.
