SCA: security update for helm.sh/helm, helm.sh/helm/v3 (GHSA-c52f-pq47-2r9j)

medium Tenable Cloud Security Plugin ID 431931

Description

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

 - In Helm before versions 2.16.11 and 3.3.2, a Helm plugin can contain duplicates of the same entry, with
 the last one always used. If a plugin is compromised, this lowers the level of access that an attacker
 needs to modify a plugin's install hooks, causing a local execution attack. To perform this attack, an
 attacker must have write access to the git repository or plugin archive (.tgz) while being downloaded
 (which can occur during a MITM attack on a non-SSL connection). This issue has been patched in Helm
 2.16.11 and Helm 3.3.2. As a possible workaround make sure to install plugins using a secure connection
 protocol like SSL. (CVE-2020-15187)
