Upgrade Oracle:5 kernel-uek-debug to version 0:2.6.32-300.3.1.el5uek or higher.

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 ptrace_setxregs function in arch/xtensa/kernel/ptrace.c in the Linux kernel before 3.1 does not validate user-space pointers, which allows local users to obtain sensitive information from kernel memory locations via a crafted PTRACE_SETXTREGS request.
