Descriptions

In GNU Coreutils through 8.29, chown-core.c in chown and chgrp does not prevent replacement of a plain file with a symlink during use of the POSIX "-R -L" options, which allows local users to modify the ownership of arbitrary files by leveraging a race condition.

En GNU Coreutils hasta la versión 8.29, chown-core.c en chown y chgrp no evita que se sustituya un archivo plano con un symlink mientras se utilizan las opciones POSIX "-R -L", lo que permite a los usuarios locales modificar la propiedad de archivos arbitrarios mediante una condición de carrera.
