Descriptions

Helm is a tool for managing Charts, pre-configured Kubernetes resources. Versions prior to 3.10.3 are subject to Uncontrolled Resource Consumption, resulting in Denial of Service. Input to functions in the _strvals_ package can cause a stack overflow. In Go, a stack overflow 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. This issue has been patched in 3.10.3. SDK users can validate strings supplied by users won't create large arrays causing significant memory usage before passing them to the _strvals_ functions.

Helm es una herramienta para gestionar gráficos, recursos de Kubernetes preconfigurados. Las versiones anteriores a la 3.10.3 están sujetas a un consumo incontrolado de recursos, lo que resulta en una Denegación de Servicio (DoS). La entrada a funciones en _strvals_ package puede provocar un desbordamiento de la pila. En Go, no se puede recuperar un desbordamiento de pila. Las aplicaciones que usan funciones de _strvals_ package en Helm SDK pueden sufrir un ataque de Denegación de Servicio (DoS) cuando usan este paquete y entran en pánico. Este problema se solucionó en 3.10.3. Los usuarios del SDK pueden validar que las cadenas proporcionadas por los usuarios no creen matrices grandes que provoquen un uso significativo de la memoria antes de pasarlas a las _strvals_ functions.

A flaw was found in Helm, a tool for managing Charts, a pre-configured Kubernetes resources. Versions prior to 3.10.3 are subject to Uncontrolled Resource Consumption. Input to functions in the _strvals_ package could cause a stack overflow that is unrecoverable by Go. Applications that use functions from the _strvals_ package in Helm SDK may result in a denial of service.
