The tough library, prior to 0.12.0, does not properly sanitize delegated role names when caching a repository, or when loading a repository from the filesystem. When the repository is cached or loaded, files ending with the .json extension could be overwritten with role metadata anywhere on the system. A fix is available in version 0.12.0. No workarounds to this issue are known."

La biblioteca tough, versiones anteriores a 0.12.0, no sanea adecuadamente los nombres de los roles delegados cuando se almacena en caché un repositorio, o cuando se carga un repositorio desde el sistema de archivos. Cuando el repositorio se almacena en caché o se carga, los archivos que terminan con la extensión .json podrían sobrescribirse con metadatos de roles en cualquier parte del sistema. Una corrección está disponible en la versión 0.12.0. No se conocen soluciones a este problema"
