Descriptions
The insert_module function in runtime/staprun/staprun_funcs.c in the systemtap runtime tool (staprun) in SystemTap before 1.6 does not properly validate a module when loading it, which allows local users to gain privileges via a race condition between the signature validation and the module initialization.
La función insert_module en tiempo de ejecución/staprun/staprun_funcs.c en la herramienta de tiempo de ejecución systemtap (staprun) en SystemTap antes de v1.6 no valida correctamente un módulo cuando se carga, lo que permite a usuarios locales conseguir privilegios a través de una condición de carrera entre la validación de la firma y el módulo de inicialización.
