Detailsinfo

A vulnerability was found in Google Chrome (Web Browser) (version now known). It has been classified as problematic. This affects some unknown processing of the component HTTPS Handler.

The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality. The summary by CVE is:

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.

The weakness was presented 08/03/2016 by Mathy Vanhoef and Tom Van Goethem with iMinds-DistriNet as HEIST: HTTP Encrypted Information can be Stolen through TCP-windows as confirmed paper (Blackhat).
