MEDIA
Tipo:
CWE-269
Gestión de privilegios incorrecta
Fecha de publicación:
30/12/2010
Última modificación:

Descripción
La función do_exit en kernel/exit.c en el kernel de Linux anteriores a v2.6.36.2 no gestiona de forma adecuada el KERNEL_DS y el valor get_fs, lo que permite a usuarios locales saltarse las restricciones access_ok, sobrescribiendo posiciones de memoria del kernel, y obtener privilegios mediante el aprovechamiento de un (1) ERROR, (2) desreferencia a un puntero NULL, o (3) error de página, como lo demuestró por vectores que implican la característica clear_child_tid en las llamadas al sistema de unión.
