      "value": "An issue was found in CPython 3.12.0 `subprocess` module on POSIX platforms. The issue was fixed in CPython 3.12.1 and does not affect other stable releases.\n\nWhen using the `extra_groups=` parameter with an empty list as a value (ie `extra_groups=[]`) the logic regressed to not call `setgroups(0, NULL)` before calling `exec()`, thus not dropping the original processes' groups before starting the new process. There is no issue when the parameter isn't used or when any value is used besides an empty list.\n\nThis issue only impacts CPython processes run with sufficient privilege to make the `setgroups` system call (typically `root`).\n\n"

      "value": "Se encontr\u00f3 un problema en el m\u00f3dulo `subproceso` de CPython 3.12.0 en plataformas POSIX. El problema se solucion\u00f3 en CPython 3.12.1 y no afecta a otras versiones estables. Cuando se utiliza el par\u00e1metro `extra_groups=` con una lista vac\u00eda como valor (es decir, `extra_groups=[]`), la l\u00f3gica retrocede para no llamar a `setgroups(0, NULL)` antes de llamar a `exec()`, por lo que no se descarta el grupos de procesos originales antes de iniciar el nuevo proceso. No hay ning\u00fan problema cuando no se usa el par\u00e1metro o cuando se usa cualquier valor adem\u00e1s de una lista vac\u00eda. Este problema solo afecta los procesos de CPython que se ejecutan con privilegios suficientes para realizar la llamada al sistema \"setgroups\" (normalmente \"root\")."
