Summary
An issue was discovered in the Dask distributed package before 2021.10.0 for Python. Single machine Dask clusters started with dask.distributed.LocalCluster or dask.distributed.Client (which defaults to using LocalCluster) would mistakenly configure their respective Dask workers to listen on external interfaces (typically with a randomly selected high port) rather than only on localhost. A Dask cluster created using this method (when running on a machine that has an applicable port exposed) could be used by a sophisticated attacker to achieve remote code execution.

Los cl\u00fasteres Dask de una sola m\u00e1quina iniciados con dask.distributed.LocalCluster o dask.distributed.Client (que utiliza por defecto LocalCluster) configuraban por error sus respectivos Dask workers para escuchar en interfaces externas (normalmente con un puerto alto seleccionado al azar) en lugar de hacerlo s\u00f3lo en localhost. Un cluster Dask creado con este m\u00e9todo (cuando se ejecuta en una m\u00e1quina que tiene un puerto aplicable expuesto) podr\u00eda ser utilizado por un atacante sofisticado para lograr la ejecuci\u00f3n remota de c\u00f3digo"
