Description |
|
|
Se ha descubierto una vulnerabilidad en fbi 2.01-1.4. La vulnerabilidad reside en que el script "fbgs" en las utilidades "fbida", cuando la variable de entorno TMPDIR no está definida, crea ficheros temporales de forma insegura en /var/tmp/fbps-[PID]. Un atacante local podría sobrescribir ficheros arbitrarios mediante un ataque de enlace simbólico. |
