1236963: CVE-2015-2741 Mozilla: Key pinning is ignored when overridable errors are encountered (MFSA 2015-67)
It was found that Firefox skipped key-pinning checks when handling an error that could be overridden by the user (for example an expired certificate error). This flaw allowed a user to override a pinned certificate, which is an action the user should not be able to perform.
