SCA: security update for github.com/traefik/traefik/v2 (GHSA-m697-4v8f-55qg)

high Tenable Cloud Security Plugin ID 416771

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Traefik is an HTTP reverse proxy and load balancer. Prior to version 2.4.13, there exists a potential
 header vulnerability in Traefik's handling of the Connection header. Active exploitation of this issue is
 unlikely, as it requires that a removed header would lead to a privilege escalation, however, the Traefik
 team has addressed this issue to prevent any potential abuse. If one has a chain of Traefik middlewares,
 and one of them sets a request header, then sending a request with a certain Connection header will cause
 it to be removed before the request is sent. In this case, the backend does not see the request header. A
 patch is available in version 2.4.13. There are no known workarounds aside from upgrading.
 (CVE-2021-32813)
