Name of the Vulnerable Software and Affected Versions HTTP/2 protocol (affected versions not specified)

Description The issue concerns the HTTP/2 protocol, which does not account for the TCP congestion window when determining content length. This oversight allows remote attackers to exploit a web-browser configuration where third-party cookies are sent, making it easier to obtain cleartext data through a "HEIST" attack.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
