NVD Description

Note: Versions mentioned in the description apply only to the upstream istio-proxy package and not the istio-proxy package as distributed by RHEL.

When a server is configured to support unencrypted HTTP/2, it reads a few bytes from each new connection to see if they contain the HTTP/2 client preface. ReadHeaderTimeout is unexpectedly not being applied when doing this.
