ASLR^Cache or AnC: A MMU Sidechannel breaking ASLR from Javascript, and media coverage

Today we announce ASLR^Cache, a MMU sidechannel exploiting a micro-architectural property of all modern CPU models. This signal is even visible from Javascript and breaks ASLR in sandboxed environments. The name ASLR^Cache (or simply AnC) is a reference to the fact that ASLR and CPU caches are mutually exclusive on modern architectures. For more information, please see our AnC project page.
