Description Marcus Meissner 2016-12-14 13:26:11 UTC
Security vulnerabilities fixed in Firefox 50.1
https://www.mozilla.org/en-US/security/advisories/mfsa2016-94/

Discovered by: Jann Horn
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.
