CVE-2016-7153

The HTTP/2 protocol does not consider the role of the TCP congestion window in providing information about content lengt

The HTTP/2 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.
