[PoC] 透过 JavaScript 远程攻陷 Intel Core2Duo

标题下的太神了!!!JavaScript 耶!!!我没有 CPU可以试，不过根据这篇 「Intel Core2Duo CPU cache controller bug PoC」，可以透过 JavaScript 突破 application & OS 保护机制远程攻击 Intel Core2Duo。在 PoC 中提到测试过 Intel Core 2 Duo T5750 与 Intel Atom N270 。有谁有 Intel Core 2 Duo 的 CPU 来试试看。不过另外一篇 (http://news.ycombinator.com/item?id=4246338 )说是假的。 点击(此处)折叠或打开!--1-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=00 _ __ __ __ 11
