Scientific Linux Security Update : kernel on SL4.x i386/x86_64

This script is Copyright (C) 2012-2016 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

These updated packages fix the following security issues :

- A security flaw was found in the Linux kernel memory
copy routines, when running on certain AMD64 systems. If
an unsuccessful attempt to copy kernel memory from
source to destination memory locations occurred, the
copy routines did not zero the content at the
destination memory location. This could allow a local
unprivileged user to view potentially sensitive data.
(CVE-2008-2729, Important)

- Alexey Dobriyan discovered a race condition in the Linux
kernel process-tracing system call, ptrace. A local
unprivileged user could use this flaw to cause a denial
of service (kernel hang). (CVE-2008-2365, Important)

- Tavis Ormandy discovered a deficiency in the Linux
kernel 32-bit and 64-bit emulation. This could allow a
local unprivileged user to prepare and run a specially
crafted binary, which would use this deficiency to leak
uninitialized and potentially sensitive data.
(CVE-2008-0598, Important)

- It was discovered that the Linux kernel handled string
operations in the opposite way to the GNU Compiler
Collection (GCC). This could allow a local unprivileged
user to cause memory corruption. (CVE-2008-1367, Low)

As well, these updated packages fix the following bug :

- On systems with a large number of CPUs (more than 16),
multiple applications calling the 'times()' system call
may have caused a system hang.
