## Overview

In net/http in Go before 1.18.6 and 1.19.x before 1.19.1, attackers can cause a denial of service because an HTTP/2 connection can hang during closing if shutdown were preempted by a fatal error.

## Affected packages

- `golang.org/x/net < 0.0.0-20220906165146-f3363e06e74c`
- `golang.org/x/net/http2 < 0.0.0-20220906165146-f3363e06e74c`

## Remediation

Upgrade to a patched release:

- `golang.org/x/net 0.0.0-20220906165146-f3363e06e74c`
- `golang.org/x/net/http2 0.0.0-20220906165146-f3363e06e74c`
