Scientific Linux Security Update : kernel on SL7.x x86_64 (Stack Clash)

This script is Copyright (C) 2017 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

Security Fix(es) :

- A flaw was found in the way memory was being allocated
on the stack for user space binaries. If heap (or
different memory region) and stack memory regions were
adjacent to each other, an attacker could use this flaw
to jump over the stack guard gap, cause controlled
memory corruption on process stack or the adjacent
memory region, and thus increase their privileges on the
system. This is a kernel-side mitigation which increases
the stack guard gap size from one page to 1 MiB to make
successful exploitation of this issue more difficult.
