Red Hat Security Advisory

Synopsis: Important: kernel security and bug fix update
Advisory ID: RHSA-2009:1670-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1670.html
Issue date: 2009-12-15
CVE Names: CVE-2009-3612 CVE-2009-3620 CVE-2009-3621
CVE-2009-3726
=====================================================================

1. Summary:

Updated kernel packages that fix multiple security issues and several bugs
are now available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, noarch, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, noarch, x86_64

3. Description:

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

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)

Knowledgebase DOC-20536 has steps to mitigate NULL pointer dereference
flaws.

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. (BZ#539675)

* 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. (BZ#539690)

* NMI watchdog is now disabled for offline CPUs. (BZ#539691)

* 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)

Users should upgrade to these updated packages, which contain backported
patches to correct these issues. The system must be rebooted for this
update to take effect.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
