medium Tenable Self-Hosted Container Security Plugin ID 417738

Description

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

- Helm is a tool that streamlines installing and managing Kubernetes applications.`getHostByName` is a Helm
template function introduced in Helm v3. The function is able to accept a hostname and return an IP
address for that hostname. To get the IP address the function performs a DNS lookup. The DNS lookup
happens when used with `helm install|upgrade|template` or when the Helm SDK is used to render a chart.
Information passed into the chart can be disclosed to the DNS servers used to lookup the IP address. For
example, a malicious chart could inject `getHostByName` into a chart in order to disclose values to a
malicious DNS server. The issue has been fixed in Helm 3.11.1. Prior to using a chart with Helm verify the
`getHostByName` function is not being used in a template to disclose any information you do not want
passed to DNS servers. (CVE-2023-25165)
