Alpine: multiple k3s packages: security update to 1.18.3-r1 (deprecated)

medium Tenable Cloud Security Plugin ID 400383

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- The Kubernetes kube-controller-manager in versions v1.0-1.14, versions prior to v1.15.12, v1.16.9,
v1.17.5, and version v1.18.0 are vulnerable to a Server Side Request Forgery (SSRF) that allows certain
authorized users to leak up to 500 bytes of arbitrary information from unprotected endpoints within the
master's host network (such as link-local or loopback services). (CVE-2020-8555)

- A vulnerability was found in all versions of containernetworking/plugins before version 0.8.6, that allows
malicious containers in Kubernetes clusters to perform man-in-the-middle (MitM) attacks. A malicious
container can exploit this flaw by sending rogue IPv6 router advertisements to the host or other
containers, to redirect traffic to the malicious container. (CVE-2020-10749)
