Security Bulletin
Summary
Multiple browsers could allow a remote attacker to obtain sensitive information, caused by the failure to consider the role of the TCP congestion window in providing information about content length by the HTTPS protocol or by the HTTP/2 protocol. By visiting a Web site owned by a malicious party, an attacker could exploit this vulnerability to obtain e-mail addresses, social security numbers, and other small pieces of encrypted data. Note: This vulnerability is also known as a HEIST attack.
