CVE-2011-0726 Open this link in a new tabHow to fix?
Upgrade Oracle:5 kernel-uek-debug to version 0:2.6.32-100.28.15.el5 or higher.
This issue was patched in ELSA-2011-2015.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-uek-debug package and not the kernel-uek-debug package as distributed by Oracle.
See How to fix? for Oracle:5 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.
