Descriptions
In the Zstandard command-line utility prior to v1.4.1, output files were created with default permissions. Correct file permissions (matching the input) would only be set at completion time. Output files could therefore be readable or writable to unintended parties.
En la utilidad Zstandard command-line versiones anteriores a v1.4.1, los archivos de salida se creaban con permisos predeterminados. Los permisos de archivo correctos (que coincidan con la entrada) solo se establecerán en el momento de la completación. Por lo tanto, los archivos de salida podrían ser leídos o escribibles para personas no deseadas
