      "value": "Incus is a system container and virtual machine manager. Prior to version 7.0.0, user provided image and backup tarballs would be unpacked and YAML files parsed without any size restrictions. This was making it easy for an authenticated user to provide a crafted image or backup tarball that when parsed by Incus would lead to a very large YAML document being loaded into memory, potentially causing the entire server to run out of memory. This issue has been patched in version 7.0.0."

      "value": "Incus es un gestor de contenedores de sistema y máquinas virtuales. Antes de la versión 7.0.0, los tarballs de imagen y copia de seguridad proporcionados por el usuario se desempaquetaban y los archivos YAML se analizaban sin restricciones de tamaño. Esto facilitaba a un usuario autenticado proporcionar un tarball de imagen o copia de seguridad manipulado que, al ser analizado por Incus, provocaría la carga de un documento YAML muy grande en la memoria, lo que podría causar que todo el servidor se quedara sin memoria. Este problema ha sido parcheado en la versión 7.0.0."
