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."}], "lastModified": "2023-02-16T20:10:18.263", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:helm:helm:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "52B3342E-F1D8-46B9-91C1-192092207FFA", "versionEndExcluding": "3.11.1", "versionStartIncluding": "3.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
