Overview

io.netty:netty-codec-http2 is a HTTP2 sub package for the netty library, an event-driven asynchronous network application framework.

Affected versions of this package are vulnerable to Denial of Service (DoS) in the implementation of the HTTP/2 protocol. An attacker can cause a denial of service (including via DDoS) by rapidly resetting many streams through request cancellation.
