A bug was found in Moby (Docker Engine) where supplementary groups are not set up properly. If an attacker has direct access to a container and manipulates their supplementary group access, they may be able to use supplementary group access to bypass primary group restrictions in some cases, potentially gaining access to sensitive information or gaining the ability to execute code in that container. This bug is fixed in Moby (Docker Engine) 20.10.18. Running containers should be stopped and restarted for the permissions to be fixed. For users unable to upgrade, this problem can be worked around by not using the `\"USER $USERNAME\"` Dockerfile instruction. Instead by calling `ENTRYPOINT [\"su\", \"-\", \"user\"]` the supplementary groups will be set up properly."}, {"lang": "es", "value": "Moby es un proyecto de c\u00f3digo abierto creado por Docker para permitir una contenci\u00f3n de software. Ha sido encontrado un bug en Moby (Docker Engine) en el que los grupos complementarios no son configurados apropiadamente.

Este error ha sido corregido en Moby (Docker Engine) versi\u00f3n 20.10.18. Los contenedores en ejecuci\u00f3n deben ser detenidos y reiniciados para que los permisos sean corregidos.
