- javert 9y agoI think so. But I'm just inferring that from Google's security blog posting; I can't say with real expertise. Would love for an expert to chime in.
- cookiecaper 9y agoDisclaimer: I'm not a CPU designer or a kernel developer so I'm not sure I've grokked this yet, but I think I did. Someone who knows, please correct me if I'm wrong. My understanding is that Spectre will allow an attacker to read any memory anywhere in userspace, so yes, that would include the clipboard. Meltdown is just an enhancement to Spectre that allows it to also read into kernel space (ring 0). Spectre is the systemic issue that accurately deduces memory values based on CPU cache heat. Meltdown is the implementation-specific issue, which affects many ARM SKUs and virtually all Intel SKUs, that makes privileged memory susceptible to the same.
