Description Huzaifa S. Sidhpurwala 2016-12-12 22:12:21 EST

An attacker could use a JavaScript Map/Set timing attack to determine whether an atom is used by another compartment/zone in specific contexts. This could be used to leak information, such as usernames embedded in JavaScript code, across websites.
