Descriptions

Use of unsafe yaml load. Allows instantiation of arbitrary objects. The flaw itself is caused by an unsafe parsing of YAML values which happens whenever an action message is processed to be sent, and allows for the creation of Python objects. Through this flaw in the ROS core package of actionlib, an attacker with local or remote access can make the ROS Master, execute arbitrary code in Python form. Consider yaml.safe_load() instead. Located first in actionlib/tools/library.py:132. See links for more info on the bug.

El uso de una carga de yaml no segura. Permite la creación de instancias de objetos arbitrarios. El fallo en sí es causado por un análisis no seguro de los valores YAML que ocurre cada vez que un mensaje de acción es procesado para ser enviado y permite la creación de objetos de Python. A través de este fallo en el paquete central ROS de actionlib, un atacante con acceso local o remoto puede hacer que ROS Master, ejecute código arbitrario en un formulario de Python. Considere en su lugar la función yaml.safe_load(). Ubicada primero en la biblioteca actionlib/tools/library.py:132. Consulte los enlaces para más información sobre el error.
