Description Huzaifa S. Sidhpurwala 2015-08-11 02:19:34 EDT
Security researcher André Bargull reported non-configurable properties on JavaScript objects can be redefined while parsing JSON in violation of the ECMAScript 6 standard. This allows malicious web content to bypass same-origin policy by editing these properties to arbitrary values.

Red Hat would like to thank the Mozilla project for reporting this issue. Upstream acknowledges André Bargull as the original reporter.
