    Denial of Service (DoS)

    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.

    How to fix Denial of Service (DoS)?

    Upgrade io.netty:netty-codec-http2 to version 4.1.100.Final or higher.

    HTTP Request Smuggling

    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 HTTP Request Smuggling. The content-length header is not correctly validated if the request only uses a single Http2HeaderFrame with the endStream set to true. This could lead to request smuggling if the request is proxied to a remote peer and translated to HTTP/1.1. This is a follow-up of CVE-2021-21295 which did not fix this specific case.

    How to fix HTTP Request Smuggling?

    Upgrade io.netty:netty-codec-http2 to version 4.1.61.Final or higher.

    HTTP Request Smuggling

    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 HTTP Request Smuggling. If a Content-Length header is present in the original HTTP/2 request, the field is not validated by Http2MultiplexHandler as it is propagated up.

    An additional case of this vulnerability was fixed in 4.1.61.Final (CVE-2021-21409).

    How to fix HTTP Request Smuggling?

    Upgrade io.netty:netty-codec-http2 to version 4.1.60.Final or higher.
