Descriptions

An issue was discovered in Wind River VxWorks 6.9 and 7. The function ``tarExtract`` implements TAR file extraction and thereby also processes files within an archive that have relative or absolute file paths. A developer using the "tarExtract" function may expect that the function will strip leading slashes from absolute paths or stop processing when encountering relative paths that are outside of the extraction path, unless otherwise forced. This could lead to unexpected and undocumented behavior, which in general could result in a directory traversal, and associated unexpected behavior.

Se descubrió un problema en Wind River VxWorks 6.9 y 7. La función ``tarExtract`` implementa la extracción de archivos TAR y, por lo tanto, también procesa archivos dentro de un archivo que tienen rutas de archivo relativas o absolutas. Un desarrollador que utilice la función "tarExtract" puede esperar que la función elimine las barras diagonales iniciales de las rutas absolutas o detenga el procesamiento cuando encuentre rutas relativas que estén fuera de la ruta de extracción, a menos que se fuerce lo contrario. Esto podría dar lugar a un comportamiento inesperado y no documentado, que en general podría dar lugar a un Directory Traversal y un comportamiento inesperado asociado.
