Descriptions

The do_task_stat function in fs/proc/array.c in the Linux kernel before 2.6.39-rc1 does not perform an expected uid check, which makes it easier for local users to defeat the ASLR protection mechanism by reading the start_code and end_code fields in the /proc/#####/stat file for a process executing a PIE binary.

Función do_task_stat en fs/proc/array.c en el kernel de linux antes de v2.6.39-rc1 no realiza una comprobación de uid esperado, lo que hace que sea más fácil para los usuarios locales derrotar a los mecanismos de protección ASLR mediante la lectura de los campos start_code y end_code en el archivo /proc/#####/stat para un proceso ejecutando un binario PIE.
