Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
Traefik is an HTTP reverse proxy and load balancer. In affected versions 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. This vulnerability has been addressed in version 2.11.2 and 3.0.0-rc5. Users are advised to upgrade. For affected versions, this vulnerability can be mitigated by configuring the readTimeout option.
