CWE-264  (opens in a new tab)

How to fix?

Upgrade Oracle:6 perf to version 0:2.6.32-358.14.1.el6 or higher.
This issue was patched in ELSA-2013-1051.

NVD Description

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

The flush_signal_handlers function in kernel/signal.c in the Linux kernel before 3.8.4 preserves the value of the sa_restorer field across an exec operation, which makes it easier for local users to bypass the ASLR protection mechanism via a crafted application containing a sigaction system call.
