CVE-2011-0726  (opens in a new tab)
CWE-20  (opens in a new tab)

How to fix?

Upgrade Centos:6 kernel to version 0:2.6.32-71.29.1.el6 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel package and not the kernel package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

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.
