Red Hat Security Advisory

Synopsis: Important: kernel-rt security and bug fix update
Advisory ID: RHSA-2018:3586-01
Product: Red Hat Enterprise MRG for RHEL-6
Advisory URL: https://access.redhat.com/errata/RHSA-2018:3586
Issue date: 2018-11-13
CVE Names: CVE-2017-18344 CVE-2018-5391 CVE-2018-10675
CVE-2018-14634
=====================================================================

1. Summary:

An update for kernel-rt is now available for Red Hat Enterprise MRG 2.

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 MRG Realtime for RHEL 6 Server v.2 – 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.

Security Fix(es):

* A flaw named FragmentSmack was found in the way the Linux kernel handled
reassembly of fragmented IPv4 and IPv6 packets. A remote attacker could use
this flaw to trigger time and calculation expensive fragment reassembly
algorithm by sending specially crafted packets which could lead to a CPU
saturation and hence a denial of service on the system. (CVE-2018-5391)

* kernel: out-of-bounds access in the show_timer function in
kernel/time/posix-timers.c (CVE-2017-18344)

* kernel: mm: use-after-free in do_get_mempolicy function allows local DoS
or other unspecified impact (CVE-2018-10675)

* kernel: Integer overflow in Linux’s create_elf_tables function
(CVE-2018-14634)

For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
the References section.

Red Hat would like to thank Juha-Matti Tilli (Aalto University – Department
of Communications and Networking and Nokia Bell Labs) for reporting
CVE-2018-5391 and Qualys Research Labs for reporting CVE-2018-14634.

Bug Fix(es):

* The kernel-rt packages have been upgraded to the 3.10.0-693.43.1 source
tree, which provides a number of bug fixes over the previous version.
(BZ#1632422)

Red Hat Security Advisory

Synopsis: Important: kernel security and bug fix update
Advisory ID: RHSA-2018:3590-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2018:3590
Issue date: 2018-11-13
CVE Names: CVE-2017-18344 CVE-2018-5391 CVE-2018-10675
CVE-2018-14634
=====================================================================

1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 7.2
Advanced Update Support, Red Hat Enterprise Linux 7.2 Telco Extended Update
Support, and Red Hat Enterprise Linux 7.2 Update Services for SAP
Solutions.

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 Server AUS (v. 7.2) – noarch, x86_64
Red Hat Enterprise Linux Server E4S (v. 7.2) – noarch, x86_64
Red Hat Enterprise Linux Server Optional AUS (v. 7.2) – x86_64
Red Hat Enterprise Linux Server Optional E4S (v. 7.2) – x86_64
Red Hat Enterprise Linux Server Optional TUS (v. 7.2) – x86_64
Red Hat Enterprise Linux Server TUS (v. 7.2) – noarch, x86_64

3. Description:

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

Security Fix(es):

* A flaw named FragmentSmack was found in the way the Linux kernel handled
reassembly of fragmented IPv4 and IPv6 packets. A remote attacker could use
this flaw to trigger time and calculation expensive fragment reassembly
algorithm by sending specially crafted packets which could lead to a CPU
saturation and hence a denial of service on the system. (CVE-2018-5391)

* kernel: out-of-bounds access in the show_timer function in
kernel/time/posix-timers.c (CVE-2017-18344)

* kernel: mm: use-after-free in do_get_mempolicy function allows local DoS
or other unspecified impact (CVE-2018-10675)

* kernel: Integer overflow in Linux’s create_elf_tables function
(CVE-2018-14634)

For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
the References section.

Red Hat would like to thank Juha-Matti Tilli (Aalto University – Department
of Communications and Networking and Nokia Bell Labs) for reporting
CVE-2018-5391 and Qualys Research Labs for reporting CVE-2018-14634.

Bug Fix(es):

* Previously, a kernel panic occurred when the kernel tried to make an out
of bound access to the array that describes the L1 Terminal Fault (L1TF)
mitigation state on systems without Extended Page Tables (EPT) support.
This update extends the array of mitigation states to cover all the states,
which effectively prevents out of bound array access. Also, this update
enables rejecting invalid, irrelevant values, that might be erroneously
provided by the userspace. As a result, the kernel no longer panics in the
described scenario. (BZ#1629565)

* Previously, a packet was missing the User Datagram Protocol (UDP) payload
checksum during a full checksum computation, if the hardware checksum was
not applied. As a consequence, a packet with an incorrect checksum was
dropped by a peer. With this update, the kernel includes the UDP payload
checksum during the full checksum computation. As a result, the checksum is
computed correctly and the packet can be received by the peer. (BZ#1635792)

* Previously, a transform lookup through the xfrm framework could be
performed on an already transformed destination cache entry (dst_entry).
When using User Datagram Protocol (UDP) over IPv6 with a connected socket
in conjunction with Internet Protocol Security (IPsec) in Encapsulating
Security Payload (ESP) transport mode. As a consequence, invalid IPv6
fragments transmitted from the host or the kernel occasionally terminated
unexpectedly due to a socket buffer (SKB) underrun. With this update, the
xfrm lookup on an already transformed dst_entry is not possible. As a
result, using UDP iperf utility over IPv6 ESP no longer causes invalid IPv6
fragment transmissions or a kernel panic. (BZ#1639586)

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/):

=====================================================================

1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 7.3
Extended Update Support.

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 ComputeNode EUS (v. 7.3) – noarch, x86_64
Red Hat Enterprise Linux ComputeNode Optional EUS (v. 7.3) – x86_64

Red Hat Enterprise Linux Server Optional EUS (v. 7.3) – ppc64, ppc64le, x86_64

3. Description:

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

Security Fix(es):

* kernel: out-of-bounds access in the show_timer function in
kernel/time/posix-timers.c (CVE-2017-18344)

* kernel: Integer overflow in Linux’s create_elf_tables function
(CVE-2018-14634)

For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
the References section.

Red Hat would like to thank Qualys Research Labs for reporting
CVE-2018-14634.

Bug Fix(es):

* On systems running Red Hat Enterprise Linux 7.3 with Red Hat OpenShift
Container Platform 3.5, a node sometimes got into “NodeNotReady” state
after a CPU softlockup. Consequently, the node was not available. This
update fixes some scheduling latency sources in memory compaction and in
the inodes memory reclaim. As a result, nodes no longer get into
“NodeNotReady” state under the described circumstances. (BZ#1625866)

* Previously, a kernel panic occurred when the kernel tried to make an out
of bound access to the array that describes the L1 Terminal Fault (L1TF)
mitigation state on systems without Extended Page Tables (EPT) support.
This update extends the array of mitigation states to cover all the states,
which effectively prevents out of bound array access. Also, this update
enables rejecting invalid, irrelevant values, that might be erroneously
provided by the userspace. As a result, the kernel no longer panics in the
described scenario. (BZ#1629566)

* Previously, a packet was missing the User Datagram Protocol (UDP) payload
checksum during a full checksum computation, if the hardware checksum was
not applied. As a consequence, a packet with an incorrect checksum was
dropped by a peer. With this update, the kernel includes the UDP payload
checksum during the full checksum computation. As a result, the checksum is
computed correctly and the packet can be received by the peer. (BZ#1635794)

4. Solution:

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

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

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

1610958 – CVE-2017-18344 kernel: out-of-bounds access in the show_timer function in kernel/time/posix-timers.c
1624498 – CVE-2018-14634 kernel: Integer overflow in Linux’s create_elf_tables function
