CVE-2016-7152

The HTTPS protocol does not consider the role of the TCP congestion window in providing information about content length

The HTTPS protocol does not consider the role of the TCP congestion window in providing information about content length, which makes it easier for remote attackers to obtain cleartext data by leveraging a web-browser configuration in which third-party cookies are sent, aka a "HEIST" attack.
