Descriptions
fs/proc/base.c in the Linux kernel before 2.6.39.4 does not properly restrict access to /proc/#####/io files, which allows local users to obtain sensitive I/O statistics by polling a file, as demonstrated by discovering the length of another user's password.
fs/proc/base.c del kernel de Linux en versiones anteriores a la 2.6.39.4 no restringe el acceso apropiadamente a los archivos /proc/#####/io, lo que facilita a usuarios locales obtener estadísticas sobre I/O confidenciales consultando un archivo, como se ha demostrado descubriendo la lengitud de la contraseña de otro usuario.
