Описание
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.
A flaw was found in the net/http component of the Go standard library. When a server is configured to support unencrypted HTTP/2, it reads initial bytes from new connections to detect the HTTP/2 client preface. However, the ReadHeaderTimeout is not correctly applied during this process. This oversight could allow a remote attacker to maintain open connections indefinitely, potentially leading to a Denial of Service (DoS) by exhausting server resources.
Отчет
Important: Unencrypted HTTP/2 servers are susceptible to a denial of service due to improper handling of ReadHeaderTimeout during the client preface reading phase. This can lead to resource exhaustion and service unavailability in affected Red Hat products configured to support unencrypted HTTP/2.
