SCA: security update for k8s.io/kubernetes (GHSA-qh36-44jv-c8xj)

low Tenable Cloud Security Plugin ID 418134

Description

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

 - As mitigations to a report from 2019 and CVE-2020-8555, Kubernetes attempts to prevent proxied connections
 from accessing link-local or localhost networks when making user-driven connections to Services, Pods,
 Nodes, or StorageClass service providers. As part of this mitigation Kubernetes does a DNS name resolution
 check and validates that response IPs are not in the link-local (169.254.0.0/16) or localhost
 (127.0.0.0/8) range. Kubernetes then performs a second DNS resolution without validation for the actual
 connection. If a non-standard DNS server returns different non-cached responses, a user may be able to
 bypass the proxy IP restriction and access private networks on the control plane. (CVE-2020-8562)
