golang: net/http, x/net/http2: rapid stream resets can cause excessive work (CVE-2023-44487)

A flaw was found in handling multiplexed streams in the HTTP/2 protocol. A client can repeatedly make a request for a new multiplex stream and immediately send an RSTSTREAM frame to cancel it. This creates extra work for the server setting up and tearing down the streams while not hitting any...

Impact Rapidly creating and cancelling streams HEADERS frame immediately followed by RSTSTREAM without bound cause denial of service. See https://vulners.com/cve/CVE-2023-44487 for details. Patches nghttp2 v1.57.0 mitigates this vulnerability by default. Workarounds If upgrading to nghttp2 v1.57....

Important: nghttp2

Issue Overview: Envoy is a cloud-native high-performance edge/middle/service proxy. Envoy's HTTP/2 codec may leak a header map and bookkeeping structures upon receiving RSTSTREAM immediately followed by the GOAWAY frames from an upstream server. In nghttp2, cleanup of pending requests due to...

CVE-2019-9514

A flaw was found in HTTP/2. Using HEADER frames with invalid HTTP headers and queuing of response RSTSTREAM frames, an attacker could cause a flood resulting in unbounded memory growth. The highest threat from this vulnerability is to system availability...

Updated golang-googlecode-net package fixes security vulnerabilities

This code was vulnerable to ping floods, potentially leading to a denial of service. The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both...
