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\u0027t create large arrays causing significant memory usage before passing them to the _strvals_ functions.\n\n### For more information\n\nHelm\u0027s 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.",
