      "value": "Flux2 is a tool for keeping Kubernetes clusters in sync with sources of configuration, and Flux's helm-controller is a Kubernetes operator that allows one to declaratively manage Helm chart releases. Helm controller is tightly integrated with the Helm SDK. A vulnerability found in the Helm SDK that affects flux2 v0.0.17 until v0.32.0 and helm-controller v0.0.4 until v0.23.0 allows for specific data inputs to cause high memory consumption. In some platforms, this could cause the controller to panic and stop processing reconciliations. In a shared cluster multi-tenancy environment, a tenant could create a HelmRelease that makes the controller panic, denying all other tenants from their Helm releases being reconciled. Patches are available in flux2 v0.32.0 and helm-controller v0.23.0."

      "value": "Flux2 es una herramienta para mantener los clusters de Kubernetes sincronizados con las fuentes de configuraci\u00f3n, y el controlador Helm de Flux es un operador de Kubernetes que permite administrar de forma declarativa los lanzamientos de gr\u00e1ficos de Helm. Helm-controller est\u00e1 estrechamente integrado con el SDK de Helm. Una vulnerabilidad encontrada en el SDK de Helm que afecta a flux2 versiones v0.0.17 hasta v0.32.0 y a helm-controller versiones v0.0.4 hasta v0.23.0, permite que determinadas entradas de datos causen un alto consumo de memoria. En algunas plataformas, esto podr\u00eda causar que el controlador entre en p\u00e1nico y deje de procesar las conciliaciones. En un entorno de cl\u00fasteres compartidos con m\u00faltiples inquilinos, un inquilino podr\u00eda crear un HelmRelease que hace que el controlador entre en p\u00e1nico, denegando a todos los dem\u00e1s inquilinos la reconciliaci\u00f3n de sus HelmRelease. Los parches est\u00e1n disponibles en flux2 versi\u00f3n v0.32.0 y helm-controller versi\u00f3n v0.23.0"
