Traefik vulnerable to denial of service with Content-length header

There is a potential vulnerability in Traefik managing requests with `Content-length` and no `body` . Sending a `GET` request to any Traefik endpoint with the `Content-length` request header results in an indefinite hang with the default configuration. This vulnerability can be exploited by attackers to induce a denial of service. ## Patches - https://github.com/traefik/traefik/releases/tag/v2.11.2 - https://github.com/traefik/traefik/releases/tag/v3.0.0-rc5 ## Workarounds For affected versions, this vulnerability can be mitigated by configuring the [readTimeout](https://doc.traefik.io/traefik/routing/entrypoints/#respondingtimeouts) option. ## For more information If you have any questions or comments about this advisory, please [open an issue](https://github.com/traefik/traefik/issues).
