architectures, the IBRS and IBPB features are required to enable the
kernel mitigations. Ubuntu is working with Intel and AMD to provide
future microcode updates that implement IBRS and IBPB as they are made
available. Ubuntu users with a processor from a different vendor should
contact the vendor to identify necessary firmware updates. Ubuntu
will provide corresponding QEMU updates in the future for users of
self-hosted virtual environments in coordination with upstream QEMU.
Ubuntu users in cloud environments should contact the cloud provider
to confirm that the hypervisor has been updated to expose the new
CPU features to virtual machines. -----BEGIN PGP SIGNED MESSAGE-----

RESOLUTION
On January 11, Intel announced issues with an increased frequency of reboots
when using the microcodes they released to address Variant 2 of the Spectre
Vulnerability for numerous processors including Broadwell, Haswell, Skylake,
Kaby Lake, Ivybridge, and Sandybridge processors. Intel has now identified
the root cause of these issues and determined that these microcodes may
introduce reboots and other unpredictable system behavior. Due to the
severity of the potential issues that may occur when using these microcodes,
Intel is now recommending that customers discontinue their use. Additional
information is available from Intels Security Exploit Newsroom here:
<https://newsroom.intel.com/press-kits/security-exploits-intel-products/> .
HPE is in alignment with Intel in our recommendation that customers
discontinue use of System ROMs including impacted microcodes and revert to
earlier System ROM versions.
All System ROMs including impacted microcodes have been removed from the HPE
Support Site. This impacts HPE ProLiant and Synergy Gen10, Gen9, and Gen8 v2
servers as well as HPE Superdome servers for which updated System ROMs had
previously been made available. Intel is working on updated microcodes to
address these issues, and HPE will validate updated System ROMs including
these microcodes and make them available to our customers in the coming
weeks.
Mitigations for Variant 1 (Spectre) and Variant 3 (Meltdown) vulnerabilities
require only OS updates and are not impacted.
* HPE has provided a customer bulletin
<https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-a00039267en_us>
with specific instructions to obtain the udpated sytem ROM
- Note:
+ CVE-2017-5715 (Variant 2) requires that the System ROM be updated and a
vendor supplied operating system update be applied as well.
+ For CVE-2017-5753, CVE-2017-5754 (Variants 1 and 3) require only
updates of a vendor supplied operating system.
+ HPE will continue to add additional products to the list.

Red Hat Security Advisory
Synopsis: Important: kernel security update
Advisory ID: RHSA-2018:0009-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2018:0009
Issue date: 2018-01-03
=====================================================================
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 EUS (v. 7.3) - noarch, ppc64, ppc64le, s390x, 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):
An industry-wide issue was found in the way many modern microprocessor
designs have implemented speculative execution of instructions (a commonly
used performance optimization). There are three primary variants of the
issue which differ in the way the speculative execution can be exploited.
Note: This issue is present in hardware and cannot be fully fixed via
software update. The updated kernel packages provide software mitigation
for this hardware issue at a cost of potential performance penalty. Please
refer to References section for further information about this issue and
the performance impact.
In this update mitigations for x86-64 architecture are provided.
Variant CVE-2017-5753 triggers the speculative execution by performing a
bounds-check bypass. It relies on the presence of a precisely-defined
instruction sequence in the privileged code as well as the fact that memory
accesses may cause allocation into the microprocessor's data cache even for
speculatively executed instructions that never actually commit (retire). As
a result, an unprivileged attacker could use this flaw to cross the syscall
boundary and read privileged memory by conducting targeted cache
side-channel attacks. (CVE-2017-5753, Important)
Variant CVE-2017-5715 triggers the speculative execution by utilizing
branch target injection. It relies on the presence of a precisely-defined
instruction sequence in the privileged code as well as the fact that memory
accesses may cause allocation into the microprocessor's data cache even for
speculatively executed instructions that never actually commit (retire). As
a result, an unprivileged attacker could use this flaw to cross the syscall
and guest/host boundaries and read privileged memory by conducting targeted
cache side-channel attacks. (CVE-2017-5715, Important)
Variant CVE-2017-5754 relies on the fact that, on impacted microprocessors,
during speculative execution of instruction permission faults, exception
generation triggered by a faulting access is suppressed until the
retirement of the whole instruction block. In a combination with the fact
that memory accesses may populate the cache even when the block is being
dropped and never committed (executed), an unprivileged local attacker
could use this flaw to read privileged (kernel space) memory by conducting
targeted cache side-channel attacks. (CVE-2017-5754, Important)
Note: CVE-2017-5754 affects Intel x86-64 microprocessors. AMD x86-64
microprocessors are not affected by this issue.
Red Hat would like to thank Google Project Zero for reporting these issues.
4. Solution:
For details on how to apply this update, which includes the changes
described in this advisory, refer to:

CVE-2017-5753 Affected
CVE-2017-5754 Affected. CPUhardware is a set of firmware that runs in the CPU (Central Processing Unit) for managing and controlling the CPU. The Spectre vulnerability exists in the CPU processor core. Because Intel does not separate low-privileged applications from accessing kernel memory, an attacker can use a malicious application to obtain private data that should be quarantined. Intel and ARM CPU chips have an information disclosure vulnerability, which originates from a flaw in the processor data boundary mechanism. The following products and versions are affected: ARM Cortex-A75; Intel Xeon E5-1650 v3, v2, v4; Xeon E3-1265l v2, v3, v4; Xeon E3-1245 v2, v3, v5, v6; Xeon X7542 wait. By now, we're sure most everyone have heard of the Meltdown and Spectre
attacks. If not, head over to https://meltdownattack.com/ and get an
overview.
https://googleprojectzero.blogspot.com/2018/01/reading-privileged-memory-with-side.html
The FreeBSD Security Team was notified of the issue in late December
and received a briefing under NDA with the original embargo date of
January 9th. Since we received relatively late notice of the issue, our
ability to provide fixes is delayed.
Meltdown (CVE-2017-5754)
~~~~~~~~~~~~~~~~~~~~~~~~
In terms of priority, the first step is to mitigate against the Meltdown
attack (CVE-2017-5754, cited as variant 3 by Project Zero). Work for
this is ongoing, but due to the relatively large changes needed, this is
going to take a little while. We are currently targeting patches for
amd64 being dev complete this week with testing probably running into
next week. From there, we hope to give it a short bake time before
pushing it into the 11.1-RELEASE branch. Additional work will be
required to bring the mitigation to 10.3-RELEASE and 10.4-RELEASE.
The code will be selectable via a tunable which will automatically turn
on for modern Intel processors and off for AMD processors (since they
are reportedly not vulnerable). Since the fix for Meltdown does incur a
performance hit for any transition between user space and kernel space,
this could be rather impactful depending on the workload. As such, the
tunable can also be overridden by the end-user if they are willing to
accept the risk.
Initial work can be tracked at https://reviews.freebsd.org/D13797.
Please note this is a work in progress and some stuff is likely to be
broken.
Spectre (CVE-2017-5753 and CVE-2017-5715)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
When it comes to the Spectre vulnerabilities, it is much harder to sort
these out. Variant 1 (CVE-2017-5753) is going to require some static
analysis to determine vulnerable use cases that will require barriers to
stop speculation from disclosing information it shouldn't. While we
haven't done the analysis to determine where we are vulnerable, the
number of cases here are supposed to be pretty small. Apparently there
have been some Coverity rules developed to help look for these, but we
are still evaluating what can be done here.
The other half of Spectre, variant 2 (CVE-2017-5715) is a bit trickier
as it affects both normal processes and bhyve. There is a proposed patch
for LLVM (https://reviews.llvm.org/D41723) that introduces a concept
called 'retpoline' which mitigates this issue. We are likely to pull
this into HEAD and 11-STABLE once it hits the LLVM tree. Unfortunately,
the currently supported FreeBSD releases are using older versions of
LLVM for which we are not sure the LLVM project will produce patches. We
will be looking at the feasibility to backport these patches to these
earlier versions.
There are CPU microcode fixes coming out when in concert with OS changes
would also help, but that's a bit down the road at the moment.
If anything significantly changes I will make additional posts to
clarify as the information becomes available.

Red Hat Security Advisory
Synopsis: Important: redhat-virtualization-host security update
Advisory ID: RHSA-2018:0044-01
Product: Red Hat Virtualization
Advisory URL: https://access.redhat.com/errata/RHSA-2018:0044
Issue date: 2018-01-05
=====================================================================
1. Summary:
An update for redhat-virtualization-host is now available for RHEV 3.X
Hypervisor and Agents for RHEL-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:
RHEL 7-based RHEV-H - noarch
3. Description:
The ovirt-node-ng packages provide the Red Hat Virtualization Host. These
packages include redhat-release-virtualization-host, ovirt-node, and
rhev-hypervisor. Red Hat Virtualization Hosts (RHVH) are installed using a
special build of Red Hat Enterprise Linux with only the packages required
to host virtual machines. RHVH features a Cockpit user interface for
monitoring the host's resources and performing administrative tasks.
Security Fix(es):
An industry-wide issue was found in the way many modern microprocessor
designs have implemented speculative execution of instructions (a commonly
used performance optimization). There are three primary variants of the
issue which differ in the way the speculative execution can be exploited.
Note: This issue is present in hardware and cannot be fully fixed via
software update. The updated kernel packages provide software mitigation
for this hardware issue at a cost of potential performance penalty. Please
refer to References section for further information about this issue and
the performance impact.
Variant CVE-2017-5753 triggers the speculative execution by performing a
bounds-check bypass. It relies on the presence of a precisely-defined
instruction sequence in the privileged code as well as the fact that memory
accesses may cause allocation into the microprocessor's data cache even for
speculatively executed instructions that never actually commit (retire). As
a result, an unprivileged attacker could use this flaw to cross the syscall
boundary and read privileged memory by conducting targeted cache
side-channel attacks. (CVE-2017-5753, Important)
Variant CVE-2017-5715 triggers the speculative execution by utilizing
branch target injection. It relies on the presence of a precisely-defined
instruction sequence in the privileged code as well as the fact that memory
accesses may cause allocation into the microprocessor's data cache even for
speculatively executed instructions that never actually commit (retire). As
a result, an unprivileged attacker could use this flaw to cross the syscall
and guest/host boundaries and read privileged memory by conducting targeted
cache side-channel attacks. (CVE-2017-5715, Important)
Variant CVE-2017-5754 relies on the fact that, on impacted microprocessors,
during speculative execution of instruction permission faults, exception
generation triggered by a faulting access is suppressed until the
retirement of the whole instruction block. In a combination with the fact
that memory accesses may populate the cache even when the block is being
dropped and never committed (executed), an unprivileged local attacker
could use this flaw to read privileged (kernel space) memory by conducting
targeted cache side-channel attacks. (CVE-2017-5754, Important)
Note: CVE-2017-5754 affects Intel x86-64 microprocessors. AMD x86-64
microprocessors are not affected by this issue.
Red Hat would like to thank Google Project Zero for reporting these issues.

around unreachable code. (CVE-2017-17862)
Jann Horn discovered that the Berkeley Packet Filter (BPF) implementation
in the Linux kernel mishandled pointer data values in some situations.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.

Please note that fully mitigating CVE-2017-5715 (Spectre Variant 2)
requires corresponding processor microcode/firmware updates or,
in virtual environments, hypervisor updates. On i386 and amd64
architectures, the IBRS and IBPB features are required to enable the
kernel mitigations. Ubuntu is working with Intel and AMD to provide
future microcode updates that implement IBRS and IBPB as they are made
available. Ubuntu users with a processor from a different vendor should
contact the vendor to identify necessary firmware updates. Ubuntu
will provide corresponding QEMU updates in the future for users of
self-hosted virtual environments in coordination with upstream QEMU.
Ubuntu users in cloud environments should contact the cloud provider
to confirm that the hypervisor has been updated to expose the new
CPU features to virtual machines. Summary

CVE-2017-5715
Multiple researchers have discovered a vulnerability in various
processors supporting speculative execution, enabling an attacker
controlling an unprivileged process to read memory from arbitrary
addresses, including from the kernel and all other processes running on
the system.
CVE-2017-5754
Multiple researchers have discovered a vulnerability in Intel
processors, enabling an attacker controlling an unprivileged process to
read memory from arbitrary addresses, including from the kernel and all
other processes running on the system.
This specific attack has been named Meltdown and is addressed in the
Linux kernel on the powerpc/ppc64el architectures by flushing the L1
data cache on exit from kernel mode to user mode (or from hypervisor to
kernel).
This works on Power7, Power8 and Power9 processors.
CVE-2017-13166
A bug in the 32-bit compatibility layer of the v4l2 IOCTL handling code
has been found. Memory protections ensuring user-provided buffers always
point to userland memory were disabled, allowing . This bug could be
exploited by an attacker to overwrite kernel memory from an unprivileged
userland process, leading to privilege escalation.
CVE-2018-5750
An information leak has been found in the Linux kernel. The
acpi_smbus_hc_add() prints a kernel address in the kernel log at every
boot, which could be used by an attacker on the system to defeat kernel
ASLR.
Additionnaly to those vulnerability, some mitigations for CVE-2017-5753 are
included in this release.
CVE-2017-5753
Multiple researchers have discovered a vulnerability in various
processors supporting speculative execution, enabling an attacker
controlling an unprivileged process to read memory from arbitrary
addresses, including from the kernel and all other processes running on
the system.
This specific attack has been named Spectre variant 1 (bounds-check
bypass) and is mitigated in the Linux kernel architecture by identifying
vulnerable code sections (array bounds checking followed by array
access) and replacing the array access with the speculation-safe
array_index_nospec() function.
More use sites will be added over time.
For the stable distribution (stretch), these problems have been fixed in
version 4.9.82-1+deb9u2.
We recommend that you upgrade your linux packages.

Software Description:
- firefox: Mozilla Open Source web browser
Details:
It was discovered that speculative execution performed by modern CPUs
could leak information through a timing side-channel attack, and that
this could be exploited in web browser JavaScript engines. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit this to obtain sensitive information from other
domains, bypassing same-origin restrictions. (CVE-2017-5715,

CVSS V2: 1.9 CVSS V3: 5.6 Severity: MEDIUM |
Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. CPU hardware utilizing speculative execution may be vulnerable to cache timing side-channel analysis. Two vulnerabilities are identified, known as "Variant 3a" and "Variant 4". CPUhardware is a set of firmware that runs in the CPU (Central Processing Unit) for managing and controlling the CPU. The Meltdown vulnerability exists in the CPU processor core, which \"melts\" the security boundary implemented by hardware, allowing low-privileged user-level applications to \"cross-border\" access to system-level memory, causing data leakage. The following products and versions are affected: ARM Cortex-R7; Cortex-R8; Cortex-A8; Cortex-A9; Cortex-A12; Intel Xeon CPU E5-1650 v3, v2, v4 versions; Xeon E3-1265l v2, v3, v4 Version; Xeon E3-1245 v2, v3, v5, v6 versions; Xeon X7542, etc. By now, we're sure most everyone have heard of the Meltdown and Spectre

bounds-check bypass. It relies on the presence of a precisely-defined
instruction sequence in the privileged code as well as the fact that memory
accesses may cause allocation into the microprocessor's data cache even for
speculatively executed instructions that never actually commit (retire). As
a result, an unprivileged attacker could use this flaw to cross the syscall
boundary and read privileged memory by conducting targeted cache
side-channel attacks. (CVE-2017-5753, Important)
Variant CVE-2017-5715 triggers the speculative execution by utilizing
branch target injection. It relies on the presence of a precisely-defined
instruction sequence in the privileged code as well as the fact that memory
accesses may cause allocation into the microprocessor's data cache even for
speculatively executed instructions that never actually commit (retire). As
a result, an unprivileged attacker could use this flaw to cross the syscall
and guest/host boundaries and read privileged memory by conducting targeted
cache side-channel attacks. (CVE-2017-5715, Important)
Variant CVE-2017-5754 relies on the fact that, on impacted microprocessors,
during speculative execution of instruction permission faults, exception
generation triggered by a faulting access is suppressed until the
retirement of the whole instruction block. In a combination with the fact
that memory accesses may populate the cache even when the block is being
dropped and never committed (executed), an unprivileged local attacker
could use this flaw to read privileged (kernel space) memory by conducting
targeted cache side-channel attacks. (CVE-2017-5754, Important)
Note: CVE-2017-5754 affects Intel x86-64 microprocessors. AMD x86-64
microprocessors are not affected by this issue.
Red Hat would like to thank Google Project Zero for reporting these issues.

Ubuntu Security Notice USN-3620-2
April 05, 2018
linux-lts-trusty vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 ESM
Summary:
Several security issues were fixed in the Linux kernel. This update provides the corresponding updates for the Linux
Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for Ubuntu
12.04 ESM. A local attacker could use this to
expose sensitive information, including kernel memory. (CVE-2017-5715)
It was discovered that the netlink 802.11 configuration interface in the
Linux kernel did not properly validate some attributes passed from
userspace. A local attacker with the CAP_NET_ADMIN privilege could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2017-11089)
It was discovered that a buffer overflow existed in the ioctl handling code
in the ISDN subsystem of the Linux kernel. A local attacker could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2017-12762)
It was discovered that the netfilter component of the Linux did not
properly restrict access to the connection tracking helpers list. A local
attacker could use this to bypass intended access restrictions.
(CVE-2017-17448)
Dmitry Vyukov discovered that the KVM implementation in the Linux kernel
contained an out-of-bounds read when handling memory-mapped I/O. A local
attacker could use this to expose sensitive information. (CVE-2017-17741)
It was discovered that the Salsa20 encryption algorithm implementations in
the Linux kernel did not properly handle zero-length inputs. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2017-17805)
It was discovered that the keyring implementation in the Linux kernel did
not properly check permissions when a key request was performed on a
task's default keyring. A local attacker could use this to add keys to
unauthorized keyrings. (CVE-2017-17807)
It was discovered that the Broadcom NetXtremeII ethernet driver in the
Linux kernel did not properly validate Generic Segment Offload (GSO) packet
sizes. An attacker could use this to cause a denial of service (interface
unavailability). (CVE-2018-1000026)
It was discovered that the Reliable Datagram Socket (RDS) implementation in
the Linux kernel contained an out-of-bounds write during RDMA page
allocation. An attacker could use this to cause a denial of service (system
crash) or possibly execute arbitrary code. (CVE-2018-5332)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 12.04 ESM:
linux-image-3.13.0-144-generic 3.13.0-144.193~precise1
linux-image-3.13.0-144-generic-lpae 3.13.0-144.193~precise1
linux-image-generic-lpae-lts-trusty 3.13.0.144.135
linux-image-generic-lts-trusty 3.13.0.144.135
After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well. On i386 and amd64
architectures, the IBRS and IBPB features are required to enable the
kernel mitigations. Ubuntu users with a processor from a different vendor should
contact the vendor to identify necessary firmware updates. Ubuntu
will provide corresponding QEMU updates in the future for users of
self-hosted virtual environments in coordination with upstream QEMU.
Ubuntu users in cloud environments should contact the cloud provider
to confirm that the hypervisor has been updated to expose the new
CPU features to virtual machines. On amd64 and i386, new CPU
models that match the updated microcode features were added with an -IBRS
suffix. Certain environments will require guests to be switched manually to
the new CPU models after microcode updates have been applied to the host
| VAR-201801-1063 | CVE-2018-0114 | Cisco node-jose Vulnerability related to key management errors in open source libraries |
CVSS V2: 5.0 CVSS V3: 7.5 Severity: HIGH |
A vulnerability in the Cisco node-jose open source library before 0.11.0 could allow an unauthenticated, remote attacker to re-sign tokens using a key that is embedded within the token. The vulnerability is due to node-jose following the JSON Web Signature (JWS) standard for JSON Web Tokens (JWTs). This standard specifies that a JSON Web Key (JWK) representing a public key can be embedded within the header of a JWS. This public key is then trusted for verification. An attacker could exploit this by forging valid JWS objects by removing the original signature, adding a new public key to the header, and then signing the object using the (attacker-owned) private key associated with the public key embedded in that JWS header. Cisco Node-jose Library is prone to a remote security-bypass vulnerability.
Attackers can exploit this issue to bypass certain security restrictions to gain unauthorized access. This may aid in further attacks

Security Fix(es):
* An industry-wide issue was found in the way many modern microprocessor
designs have implemented speculative execution of Load & Store instructions
(a commonly used performance optimization). It relies on the presence of a
precisely-defined instruction sequence in the privileged code as well as
the fact that memory read from address to which a recent memory write has
occurred may see an older value and subsequently cause an update into the
microprocessor's data cache even for speculatively executed instructions
that never actually commit (retire). As a result, an unprivileged attacker
could use this flaw to read privileged memory by conducting targeted cache
side-channel attacks. (CVE-2018-3639)
Note: This issue is present in hardware and cannot be fully fixed via
software update. To be fully functional, up-to-date CPU
microcode applied on the system might be required. Please refer to
References section for further information about this issue, CPU microcode
requirements and the potential performance impact. Bugs fixed (https://bugzilla.redhat.com/):
1531135 - CVE-2017-18017 kernel: netfilter: use-after-free in tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c
1566890 - CVE-2018-3639 hw: cpu: speculative store bypass
6. (BZ#1549731)
* Intel Core X-Series (Skylake) processors use a hardcoded Time Stamp
Counter (TSC) frequency of 25 MHz. In some cases this can be imprecise and
lead to timing-related problems such as time drift, timers being triggered
early, or TSC clock instability. This update mitigates these problems by no
longer using the "native_calibrate_tsc()" function to define the TSC
frequency. Refined calibration is now used to update the clock rate
accordingly in these cases. (BZ#1547854)

CVE-2018-1000199
Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service or information
leaks.
CVE-2015-9016
Ming Lei reported a race condition in the multiqueue block layer
(blk-mq). On a system with a driver using blk-mq (mtip32xx,
null_blk, or virtio_blk), a local user might be able to use this
for denial of service or possibly for privilege escalation.
CVE-2017-0861
Robb Glasser reported a potential use-after-free in the ALSA (sound)
PCM core. We believe this was not possible in practice.
CVE-2017-5715
Multiple researchers have discovered a vulnerability in various
processors supporting speculative execution, enabling an attacker
controlling an unprivileged process to read memory from arbitrary
addresses, including from the kernel and all other processes
running on the system.
This specific attack has been named Spectre variant 2 (branch
target injection) and is mitigated for the x86 architecture (amd64
and i386) by using the "retpoline" compiler feature which allows
indirect branches to be isolated from speculative execution.
CVE-2017-5753
Multiple researchers have discovered a vulnerability in various
processors supporting speculative execution, enabling an attacker
controlling an unprivileged process to read memory from arbitrary
addresses, including from the kernel and all other processes
running on the system.
This specific attack has been named Spectre variant 1
(bounds-check bypass) and is mitigated by identifying vulnerable
code sections (array bounds checking followed by array access) and
replacing the array access with the speculation-safe
array_index_nospec() function.
More use sites will be added over time.
CVE-2017-13166
A bug in the 32-bit compatibility layer of the v4l2 ioctl handling
code has been found. Memory protections ensuring user-provided
buffers always point to userland memory were disabled, allowing
destination addresses to be in kernel space. On a 64-bit kernel a
local user with access to a suitable video device can exploit this
to overwrite kernel memory, leading to privilege escalation.
CVE-2017-13220
Al Viro reported that the Bluetooth HIDP implementation could
dereference a pointer before performing the necessary type check.
A local user could use this to cause a denial of service.
CVE-2017-16526
Andrey Konovalov reported that the UWB subsystem may dereference
an invalid pointer in an error case. A local user might be able
to use this for denial of service.
CVE-2017-16911
Secunia Research reported that the USB/IP vhci_hcd driver exposed
kernel heap addresses to local users. This information could aid the
exploitation of other vulnerabilities.
CVE-2017-16912
Secunia Research reported that the USB/IP stub driver failed to
perform a range check on a received packet header field, leading
to an out-of-bounds read. A remote user able to connect to the
USB/IP server could use this for denial of service.
CVE-2017-16913
Secunia Research reported that the USB/IP stub driver failed to
perform a range check on a received packet header field, leading
to excessive memory allocation. A remote user able to connect to
the USB/IP server could use this for denial of service.
CVE-2017-16914
Secunia Research reported that the USB/IP stub driver failed to
check for an invalid combination of fields in a received packet,
leading to a null pointer dereference. A remote user able to
connect to the USB/IP server could use this for denial of service.
CVE-2017-18017
Denys Fedoryshchenko reported that the netfilter xt_TCPMSS module
failed to validate TCP header lengths, potentially leading to a
use-after-free. If this module is loaded, it could be used by a
remote attacker for denial of service or possibly for code
execution.
CVE-2017-18203
Hou Tao reported that there was a race condition in creation and
deletion of device-mapper (DM) devices. A local user could
potentially use this for denial of service.
CVE-2017-18216
Alex Chen reported that the OCFS2 filesystem failed to hold a
necessary lock during nodemanager sysfs file operations,
potentially leading to a null pointer dereference. A local user
could use this for denial of service.
CVE-2017-18232
Jason Yan reported a race condition in the SAS (Serial-Attached
SCSI) subsystem, between probing and destroying a port. This
could lead to a deadlock.
CVE-2017-18241
Yunlei He reported that the f2fs implementation does not properly
initialise its state if the "noflush_merge" mount option is used.
A local user with access to a filesystem mounted with this option
could use this to cause a denial of service.
CVE-2018-1066
Dan Aloni reported to Red Hat that the CIFS client implementation
would dereference a null pointer if the server sent an invalid
response during NTLMSSP setup negotiation. This could be used
by a malicious server for denial of service.
CVE-2018-1068
The syzkaller tool found that the 32-bit compatibility layer of
ebtables did not sufficiently validate offset values. On a 64-bit
kernel, a local user with the CAP_NET_ADMIN capability (in any user
namespace) could use this to overwrite kernel memory, possibly
leading to privilege escalation. Debian disables unprivileged user
namespaces by default.
CVE-2018-1092
Wen Xu reported that a crafted ext4 filesystem image would
trigger a null dereference when mounted. A local user able
to mount arbitrary filesystems could use this for denial of
service.
CVE-2018-5332
Mohamed Ghannam reported that the RDS protocol did not
sufficiently validate RDMA requests, leading to an out-of-bounds
write. A local attacker on a system with the rds module loaded
could use this for denial of service or possibly for privilege
escalation.
CVE-2018-5333
Mohamed Ghannam reported that the RDS protocol did not properly
handle an error case, leading to a null pointer dereference. A
local attacker on a system with the rds module loaded could
possibly use this for denial of service.
CVE-2018-5750
Wang Qize reported that the ACPI sbshc driver logged a kernel heap
address. This information could aid the exploitation of other
vulnerabilities.
CVE-2018-5803
Alexey Kodanev reported that the SCTP protocol did not range-check
the length of chunks to be created. A local or remote user could
use this to cause a denial of service.
CVE-2018-6927
Li Jinyue reported that the FUTEX_REQUEUE operation on futexes did
not check for negative parameter values, which might lead to a
denial of service or other security impact.
CVE-2018-7492
The syzkaller tool found that the RDS protocol was lacking a null
pointer check. A local attacker on a system with the rds module
loaded could use this for denial of service.
CVE-2018-7566
Fan LongFei reported a race condition in the ALSA (sound)
sequencer core, between write and ioctl operations. This could
lead to an out-of-bounds access or use-after-free. A local user
with access to a sequencer device could use this for denial of
service or possibly for privilege escalation.
CVE-2018-7740
Nic Losby reported that the hugetlbfs filesystem's mmap operation
did not properly range-check the file offset. A local user with
access to files on a hugetlbfs filesystem could use this to cause
a denial of service.
CVE-2018-7757
Jason Yan reported a memory leak in the SAS (Serial-Attached
SCSI) subsystem. A local user on a system with SAS devices
could use this to cause a denial of service.
CVE-2018-7995
Seunghun Han reported a race condition in the x86 MCE
(Machine Check Exception) driver. This is unlikely to have
any security impact.
CVE-2018-8781
Eyal Itkin reported that the udl (DisplayLink) driver's mmap
operation did not properly range-check the file offset. A local
user with access to a udl framebuffer device could exploit this to
overwrite kernel memory, leading to privilege escalation.
CVE-2018-8822
Dr Silvio Cesare of InfoSect reported that the ncpfs client
implementation did not validate reply lengths from the server. An
ncpfs server could use this to cause a denial of service or
remote code execution in the client.
CVE-2018-1000004
Luo Quan reported a race condition in the ALSA (sound) sequencer
core, between multiple ioctl operations. This could lead to a
deadlock or use-after-free. A local user with access to a
sequencer device could use this for denial of service or possibly
for privilege escalation.
CVE-2018-1000199
Andy Lutomirski discovered that the ptrace subsystem did not
sufficiently validate hardware breakpoint settings. Local users
can use this to cause a denial of service, or possibly for
privilege escalation, on x86 (amd64 and i386) and possibly other
architectures.

After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
