| summary: Denial of service in string value parsing in helm.sh/helm/v3 |
| description: |- |
| Applications that use the strvals package in the Helm SDK to parse user supplied |
| input can suffer a Denial of Service when that input causes an error that cannot |
| be recovered from. |
| |
| The 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 can cause a stack overflow to be created causing a |
| stack overflow error. Stack overflow errors cannot be recovered from. |
| |
| The Helm Client will panic with input to --set, --set-string, and other value |
| setting flags that causes a stack overflow. Helm is not a long running service |
| so the error will not affect future uses of the Helm client. |
