Descripción |
|
|
Se han descubierto dos errores de programación en el programa utempter que podrían suponer potenciales agujeros de seguridad: 1) Una vulnerabilidad de directorio transversal en la ruta al dispositivo. Una ruta especialmente diseñada (que haga uso de las secuencias /../, /./ o //) podría permitir a un atacante local sobreescribir archivos del sistema mediante ataques de enlace simbólico. 2) Varias llamadas a strncpy sin finalización posterior de las cadenas, lo que provoca, en el mejor de los casos, la interrupción de utempter. |
