A bug was found in containerd prior to versions 1.6.18 and 1.5.18 where supplementary groups are not set up properly inside a container. 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. Downstream applications that use the containerd client library may be affected as well.\n\nThis bug has been fixed in containerd v1.6.18 and v.1.5.18. Users should update to these versions and recreate containers to resolve this issue. Users who rely on a downstream application that uses containerd's client library should check that application for a separate advisory and instructions. As a workaround, ensure that the `\"USER $USERNAME\"` Dockerfile instruction is not used. Instead, set the container entrypoint to a value similar to `ENTRYPOINT [\"su\", \"-\", \"user\"]` to allow `su` to properly set up supplementary groups."}, {"lang": "es", "value": "Containerd es contenedor de c\u00f3digo abierto en tiempo de ejecuci\u00f3n.

Si un atacante tiene acceso directo a un contenedor y manipula su acceso de grupo suplementario, es posible que pueda utilizar el acceso de grupo suplementario para eludir las restricciones del grupo primario en algunos casos, obteniendo potencialmente acceso a informaci\u00f3n confidencial o obteniendo la capacidad de ejecutar c\u00f3digo en ese contenedor.
