Descriptions

In Helm 2.x before 2.15.2, commands that deal with loading a chart as a directory or packaging a chart provide an opportunity for a maliciously designed chart to include sensitive content such as /etc/passwd, or to execute a denial of service (DoS) via a special file such as /dev/urandom, via symlinks. No version of Tiller is known to be impacted. This is a client-only issue.

En Helm versiones 2.x anteriores a 2.15.2, los comandos que se ocupan de cargar un gráfico como un directorio o empaquetar un gráfico ofrecen la oportunidad de que un gráfico diseñado con fines maliciosos incluya contenido confidencial tal y como /etc/passwd o ejecute una denegación de servicio (DoS) por medio de un archivo especial tal y como /dev/urandom, por medio de enlaces simbólicos. No se conoce que ninguna versión de Tiller esté afectada. Este es un problema solo del cliente.
