## Overview

### Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-7v4p-328v-8v5g. This link is maintained to preserve external references.

### Original DescriptionTraefik before 2.10.5 and 3.0.0-beta4 is affected by a denial-of-service vulnerability in HTTP/2 request handling inherited from the Go standard library's HTTP/2 implementation (CVE-2023-44487 / CVE-2023-39325, the 'Rapid Reset' technique). A remote attacker can rapidly create and cancel HTTP/2 streams to exhaust server resources and cause service unavailability.

## Affected packages

- `github.com/traefik/traefik < 2.10.5`

## Remediation

Upgrade to a patched release:

- `github.com/traefik/traefik 2.10.5`
