Out of memory panics cannot be recovered from. Applications that use functions from the `_strvals_` package in the Helm SDK can have a Denial of Service attack when they use this package and it panics.\n\n### Impact\n\nThe `_strvals_` package contains a parser that turns strings into Go structures. For example, the Helm client has command line flags like `--set`, `--set-string`, and others that enable the user to pass in strings that are merged into the values. The `_strvals_` package converts these strings into structures Go can work with. Some string inputs can cause array data structures to be created causing an out of memory panic.\n\nApplications that use the `_strvals_` package in the Helm SDK to parse user supplied input can suffer a Denial of Service when that input causes a panic that cannot be recovered from.\n\nThe Helm Client will panic with input to `--set`, `--set-string`, and other value setting flags that causes an out of memory panic. Helm is not a long running service so the panic will not affect future uses of the Helm client.\n\n### Patches\n\nThis issue has been resolved in 3.9.4. \n\n### Workarounds\n\nSDK users can validate strings supplied by users won't create large arrays causing significant memory usage before passing them to the `_strvals_` functions.\n\n### For more information\n\nHelm's security policy is spelled out in detail in our [SECURITY](https://github.com/helm/community/blob/master/SECURITY.md) document.\n\n### Credits\n\nDisclosed by Ada Logics in a fuzzing audit sponsored by CNCF.","affected":[{"package":{"name":"helm.sh/helm/v3","ecosystem":"Go","purl":"pkg:golang/helm.sh/helm/v3"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.9.4"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/08/GHSA-7hfp-qfw3-5jxh/GHSA-7hfp-qfw3-5jxh.json"}}],"references":[{"type":"WEB","url":"https://github.com/helm/helm/security/advisories/GHSA-7hfp-qfw3-5jxh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-36055"},{"type":"WEB","url":"https://github.com/helm/helm/commit/10466e3e179cc8cad4b0bb451108d3c442c69fbc"},{"type":"PACKAGE","url":"https://github.com/helm/helm"},{"type":"WEB","url":"https://github.com/helm/helm/releases/tag/v3.9.4"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2022-0962"}],"database_specific":{"cwe_ids":["CWE-400","CWE-770"],"github_reviewed":true,"github_reviewed_at":"2022-08-30T20:52:31Z","nvd_published_at":"2022-09-01T13:15:00Z","severity":"MODERATE"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
