summary: Denial of service through 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 a panic 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 array data structures to be created causing an out
    of memory panic.

    The 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.
