CVE-2022-23526

Helm is a tool for managing Charts, pre-configured Kubernetes resources. Versions prior to 3.10.3 are subject to NULL Pointer Dereference in the_chartutil_ package that can cause a segmentation violation. The _chartutil_ package contains a parser that loads a JSON Schema validation file. For example, the Helm client when rendering a chart will validate its values with the schema file. The _chartutil_ package parses the schema file and loads it into structures Go can work with. Some schema files can cause array data structures to be created causing a memory violation. Applications that use the _chartutil_ package in the Helm SDK to parse a schema file can suffer a Denial of Service when that input causes a panic that cannot be recovered from. Helm is not a long running service so the panic will not affect future uses of the Helm client. This issue has been patched in 3.10.3. SDK users can validate schema files that are correctly formatted before passing them to the _chartutil_ functions.

Summary		(es) Helm es una herramienta para gestionar Charts, recursos de Kubernetes preconfigurados. Las versiones anteriores a la 3.10.3 están sujetas a la desreferencia del puntero NULL en the_chartutil_ package, lo que puede provocar una infracción de segmentación. El paquete _chartutil_ contiene un analizador que carga un archivo de validación de JSON Schema. Por ejemplo, el cliente Helm, al representar un chart, validará sus valores con el archivo de schema. El paquete _chartutil_ analiza el archivo de schema y lo carga en estructuras con las que Go puede trabajar. Algunos archivos de schema pueden provocar la creación de estructuras de datos de matriz, lo que provoca una violación de la memoria. Las aplicaciones que utilizan el paquete _chartutil_ en Helm SDK para analizar un archivo de schema pueden sufrir una Denegación de Servicio (DoS) cuando esa entrada provoca un pánico del que no se puede recuperar. Helm no es un servicio de larga duración, por lo que el pánico no afectará los usos futuros del cliente Helm. Este problema se solucionó en 3.10.3. Los usuarios del SDK pueden validar archivos de schema que estén formateados correctamente antes de pasarlos a las funciones _chartutil_.
