Scientific Linux Security Update : kernel on SL5.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 :

Security fixes :

- NULL pointer dereference flaws in the r128 driver.
Checks to test if the Concurrent Command Engine state
was initialized were missing in private IOCTL functions.
An attacker could use these flaws to cause a local
denial of service or escalate their privileges.
(CVE-2009-3620, Important)

- a NULL pointer dereference flaw in the NFSv4
implementation. Several NFSv4 file locking functions
failed to check whether a file had been opened on the
server before performing locking operations on it. A
local user on a system with an NFSv4 share mounted could
possibly use this flaw to cause a denial of service or
escalate their privileges. (CVE-2009-3726, Important)

- a flaw in tcf_fill_node(). A certain data structure in
this function was not initialized properly before being
copied to user-space. This could lead to an information
leak. (CVE-2009-3612, Moderate)

- unix_stream_connect() did not check if a UNIX domain
socket was in the shutdown state. This could lead to a
deadlock. A local, unprivileged user could use this flaw
to cause a denial of service. (CVE-2009-3621, Moderate)

Bug fixes :

- frequently changing a CPU between online and offline
caused a kernel panic on some systems. (BZ#545583)

- for the LSI Logic LSI53C1030 Ultra320 SCSI controller,
read commands sent could receive incorrect data,
preventing correct data transfer. (BZ#529308)

- pciehp could not detect PCI Express hot plug slots on
some systems. (BZ#530383)

- soft lockups: inotify race and contention on
dcache_lock. (BZ#533822, BZ#537019)

- priority ordered lists are now used for threads waiting
for a given mutex. (BZ#533858)

- a deadlock in DLM could cause GFS2 file systems to lock
up. (BZ#533859)

- use-after-free bug in the audit subsystem crashed
certain systems when running usermod. (BZ#533861)

- on certain hardware configurations, a kernel panic when
the Broadcom iSCSI offload driver (bnx2i.ko and cnic.ko)
was loaded. (BZ#537014)

- qla2xxx: Enabled MSI-X, and correctly handle the module
parameter to control it. This improves performance for
certain systems. (BZ#537020)

- system crash when reading the cpuaffinity file on a
system. (BZ#537346)

- suspend-resume problems on systems with lots of logical
CPUs, e.g. BX-EX. (BZ#539674)

- off-by-one error in the legacy PCI bus check.

- TSC was not made available on systems with
multi-clustered APICs. This could cause slow performance
for time-sensitive applications. (BZ#539676)

- ACPI: ARB_DISABLE now disabled on platforms that do not
need it. (BZ#539677)

- fix node to core and power-aware scheduling issues, and
a kernel panic during boot on certain AMD Opteron
processors. (BZ#539678, BZ#540469, BZ#539680, BZ#539682)

- APIC timer interrupt issues on some AMD Opteron systems
prevented achieving full power savings. (BZ#539681)

- general OProfile support for some newer Intel
processors. (BZ#539683)

- system crash during boot when NUMA is enabled on systems
using MC and kernel-xen. (BZ#539684)

- on some larger systems, performance issues due to a
spinlock. (BZ#539685)

- APIC errors when IOMMU is enabled on some AMD Opteron
systems. (BZ#539687)

- on some AMD Opteron systems, repeatedly taking a CPU
offline then online caused a system hang. (BZ#539688)

- I/O page fault errors on some systems. (BZ#539689)

- certain memory configurations could cause the kernel-xen
kernel to fail to boot on some AMD Opteron systems.

- NMI watchdog is now disabled for offline CPUs.

- duplicate directories in /proc/acpi/processor/ on BX-EX
systems. (BZ#539692)

- links did not come up when using bnx2x with certain
Broadcom devices. (BZ#540381)

The system must be rebooted for this update to take effect.
