Descriptions

In package github.com/sassoftware/go-rpmutils/cpio before version 0.1.0, the CPIO extraction functionality doesn't sanitize the paths of the archived files for leading and non-leading ".." which leads in file extraction outside of the current directory. Note: the fixing commit was applied to all affected versions which were re-released.

En el paquete github.com/sassoftware/go-rpmutils/cpio anterior a la versión 0.1.0, la funcionalidad de extracción de CPIO, no sanea las rutas de los archivos archivados conduciendo o no "..", lo que conlleva a una extracción de archivos fuera del directorio actual. Nota: la confirmación de la corrección fue aplicada a todas las versiones afectadas que se volvieron a publicar
