SCA: security update for github.com/traefik/traefik/v2 (GHSA-hrhx-6h34-j5hc)

high Tenable Cloud Security Plugin ID 415926

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 2.6.1, Traefik skips the router
transport layer security (TLS) configuration when the host header is a fully qualified domain name (FQDN).
For a request, the TLS configuration choice can be different than the router choice, which implies the use
of a wrong TLS configuration. When sending a request using FQDN handled by a router configured with a
dedicated TLS configuration, the TLS configuration falls back to the default configuration that might not
correspond to the configured one. If the CNAME flattening is enabled, the selected TLS configuration is
the SNI one and the routing uses the CNAME value, so this can skip the expected TLS configuration. Version
2.6.1 contains a patch for this issue. As a workaround, one may add the FDQN to the host rule. However,
there is no workaround if the CNAME flattening is enabled. (CVE-2022-23632)
