Such a race condition could lead to implicit directory creation with permissions 0777 (without the sticky bit), which means that any low-privileged local user can delete and rename files inside those directories."}, {"lang": "es", "value": "Libarchive hasta la versi\u00f3n 3.6.2 puede hacer que los directorios tengan permisos de escritura global. La llamada \"umask()\" dentro del archivo \"archive_write_disk_posix.c\" cambia la m\u00e1scara de usuario de todo el proceso durante un periodo de tiempo muy corto; una condici\u00f3n de carrera con otro hilo puede llevar a un ajuste permanente de la m\u00e1scara de usuario a 0. Tal condici\u00f3n de carrera podr\u00eda llevar a la creaci\u00f3n impl\u00edcita de directorios con permisos 0777, sin el bit adhesivo (\"sticky bit\"), lo que significa que cualquier usuario local con pocos privilegios puede borrar y renombrar archivos dentro de esos directorios.
