3. Description:

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

Security Fix(es):

* A security flaw was found in the Linux kernel in the mark_source_chains()
function in "net/ipv4/netfilter/ip_tables.c". It is possible for a
user-supplied "ipt_entry" structure to have a large "next_offset" field.
This field is not bounds checked prior to writing to a counter value at the
supplied offset. (CVE-2016-3134, Important)

* A flaw was discovered in processing setsockopt for 32 bit processes on 64
bit systems. This flaw will allow attackers to alter arbitrary kernel
memory when unloading a kernel module. This action is usually restricted to
root-privileged users but can also be leveraged if the kernel is compiled
with CONFIG_USER_NS and CONFIG_NET_NS and the user is granted elevated
privileges. (CVE-2016-4997, Important)

* An out-of-bounds heap memory access leading to a Denial of Service, heap
disclosure, or further impact was found in setsockopt(). The function call
is normally restricted to root, however some processes with cap_sys_admin
may also be able to trigger this flaw in privileged container environments.
(CVE-2016-4998, Moderate)

Bug Fix(es):

* In some cases, running the ipmitool command caused a kernel panic due to
a race condition in the ipmi message handler. This update fixes the race
condition, and the kernel panic no longer occurs in the described scenario.
(BZ#1353947)

* Previously, running I/O-intensive operations in some cases caused the
system to terminate unexpectedly after a null pointer dereference in the
kernel. With this update, a set of patches has been applied to the 3w-9xxx
and 3w-sas drivers that fix this bug. As a result, the system no longer
crashes in the described scenario. (BZ#1362040)

* Previously, the Stream Control Transmission Protocol (SCTP) sockets did
not inherit the SELinux labels properly. As a consequence, the sockets were
labeled with the unlabeled_t SELinux type which caused SCTP connections to
fail. The underlying source code has been modified, and SCTP connections
now works as expected. (BZ#1354302)

* Previously, the bnx2x driver waited for transmission completions when
recovering from a parity event, which substantially increased the recovery
time. With this update, bnx2x does not wait for transmission completion in
the described circumstances. As a result, the recovery of bnx2x after a
parity event now takes less time. (BZ#1351972)

Enhancement(s):

* With this update, the audit subsystem enables filtering of processes by
name besides filtering by PID. Users can now audit by executable name (with
the "-F exe=<path-to-executable>" option), which allows expression of many
new audit rules. This functionality can be used to create events when
specific applications perform a syscall. (BZ#1345774)

* With this update, the Nonvolatile Memory Express (NVMe) and the
multi-queue block layer (blk_mq) have been upgraded to the Linux 4.5
upstream version. Previously, a race condition between timeout and freeing
request in blk_mq occurred, which could affect the blk_mq_tag_to_rq()
function and consequently a kernel oops could occur. The provided patch
fixes this race condition by updating the tags with the active request. The
patch simplifies blk_mq_tag_to_rq() and ensures that the two requests are
not active at the same time. (BZ#1350352)

* The Hyper-V storage driver (storvsc) has been upgraded from upstream.
This update provides moderate performance improvement of I/O operations
when using storvscr for certain workloads. (BZ#1360161)

                   Red Hat Security Advisory

Synopsis:          Important: kernel-rt security and bug fix update
Advisory ID:       RHSA-2016:1875-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2016-1875.html
Issue date:        2016-09-14
CVE Names:         CVE-2016-3134 CVE-2016-4997 CVE-2016-4998 
=====================================================================

1. Summary:

An update for kernel-rt is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Realtime (v. 7) - noarch, x86_64
Red Hat Enterprise Linux for Real Time for NFV (v. 7) - noarch, x86_64

3. Description:

The kernel-rt packages provide the Real Time Linux Kernel, which enables
fine-tuning for systems with extremely high determinism requirements.

The kernel-rt packages have been upgraded to the kernel-3.10.0-327.36.1
source tree, which provides a number of bug fixes over the previous
version. (BZ#1366538)

Security Fix(es):

* A security flaw was found in the Linux kernel in the mark_source_chains()
function in "net/ipv4/netfilter/ip_tables.c". It is possible for a
user-supplied "ipt_entry" structure to have a large "next_offset" field.
This field is not bounds checked prior to writing to a counter value at the
supplied offset. (CVE-2016-3134, Important)

* A flaw was discovered in processing setsockopt for 32 bit processes on 64
bit systems. This flaw will allow attackers to alter arbitrary kernel
memory when unloading a kernel module. This action is usually restricted to
root-privileged users but can also be leveraged if the kernel is compiled
with CONFIG_USER_NS and CONFIG_NET_NS and the user is granted elevated
privileges. (CVE-2016-4997, Important)

* An out-of-bounds heap memory access leading to a Denial of Service, heap
disclosure, or further impact was found in setsockopt(). The function call
is normally restricted to root, however some processes with cap_sys_admin
may also be able to trigger this flaw in privileged container environments.
(CVE-2016-4998, Moderate)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

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

5. Bugs fixed (https://bugzilla.redhat.com/):

1317383 - CVE-2016-3134 kernel: netfilter: missing bounds check in ipt_entry structure
1349722 - CVE-2016-4997 kernel: compat IPT_SO_SET_REPLACE setsockopt
1349886 - CVE-2016-4998 kernel: out of bounds reads when processing IPT_SO_SET_REPLACE setsockopt
