Ubuntu Security Notice 3523-1 - Jann Horn discovered that microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized memory reads via sidechannel attacks. This flaw is known as Meltdown. A local attacker could use this to expose sensitive information, including kernel memory. Jann Horn discovered that the Berkeley Packet Filter implementation in the Linux kernel did not properly check the relationship between pointer values and the BPF stack. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.

linux vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 17.10

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux: Linux kernel

Details:

Jann Horn discovered that microprocessors utilizing speculative execution
and indirect branch prediction may allow unauthorized memory reads via
sidechannel attacks. This flaw is known as Meltdown. A local attacker could
use this to expose sensitive information, including kernel memory.
(CVE-2017-5754)

Jann Horn discovered that the Berkeley Packet Filter (BPF) implementation
in the Linux kernel did not properly check the relationship between pointer
values and the BPF stack. A local attacker could use this to cause a denial
of service (system crash) or possibly execute arbitrary code.
(CVE-2017-17863)

Jann Horn discovered that the Berkeley Packet Filter (BPF) implementation
in the Linux kernel improperly performed sign extension in some situations.
A local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2017-16995)

Alexei Starovoitov discovered that the Berkeley Packet Filter (BPF)
implementation in the Linux kernel contained a branch-pruning logic issue
around unreachable code. A local attacker could use this to cause a denial
of service. (CVE-2017-17862)

Jann Horn discovered that the Berkeley Packet Filter (BPF) implementation
in the Linux kernel mishandled pointer data values in some situations. A
local attacker could use this to to expose sensitive information (kernel
memory). (CVE-2017-17864)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 17.10:
  linux-image-4.13.0-25-generic   4.13.0-25.29
  linux-image-4.13.0-25-lowlatency  4.13.0-25.29
  linux-image-generic             4.13.0.25.26
  linux-image-lowlatency          4.13.0.25.26

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.

Red Hat Security Advisory 2018-0502-01 - The kernel-alt packages provide the Linux kernel version 4.x. Multiple security issues have been addressed.

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

=====================================================================
                   Red Hat Security Advisory

Synopsis:          Important: kernel-alt security and bug fix update
Advisory ID:       RHSA-2018:0502-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2018:0502
Issue date:        2018-03-13
CVE Names:         CVE-2017-16994 CVE-2017-17712 
=====================================================================

1. Summary:

An update for kernel-alt 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 for ARM and IBM Power LE (POWER9) Server (v. 7) - aarch64, noarch, ppc64le
Red Hat Enterprise Linux for ARM and IBM Power LE (POWER9) Server Optional (v. 7) - aarch64, noarch, ppc64le

3. Description:

The kernel-alt packages provide the Linux kernel version 4.x.

Security Fix(es):

* hw: cpu: speculative execution permission faults handling (CVE-2017-5754,
Important)(ppc only)

* kernel: Race condition in raw_sendmsg function allows denial-of-service
or kernel addresses leak (CVE-2017-17712, Important)

* kernel: mm/pagewalk.c:walk_hugetlb_range function mishandles holes in
hugetlb ranges causing information leak (CVE-2017-16994, Moderate)

Bug Fix(es):

* When changing the Maximum Transmission Unit (MTU) size on Broadcom
BCM5717, BCM5718 and BCM5719 chipsets, the tg3 driver sometimes lost
synchronization with the device. Consequently, the device became
unresponsive. With this update, tg3 has been fixed, and devices no longer
hang due to this behavior. (BZ#1533478)

* Previously, the perf tool used strict string matching to provide related
events to a particular CPUID instruction. Consequently, the events were not
available on certain IBM PowerPC systems. This update fixes perf to use
regular expressions instead of string matching of the entire CPUID string.
As a result, the perf tool now supports events on IBM PowerPC architectures
as expected. (BZ#1536567)

* Previously, the kernel debugfs file system implemented removal protection
based on sleepable read-copy-update (SRCU), which slowed down the drivers
relying on the debugfs_remove_recursive() function. Consequently, a
decrease in performance or a deadlock sometimes occurred. This update
implements per-file removal protection in debugfs. As a result, the
performance of the system has improved significantly. (BZ#1538030)

* When running the 'perf test' command on a PowerKVM guest multiple times,
the branch instructions recorded in Branch History Rolling Buffer (BHRB)
entries were sometimes unmapped before the kernel processed the entries.
Consequently, the operating system terminated unexpectedly. This update
fixes the bug, and the operating system no longer crashes in the described
situation. (BZ#1538031)

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

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

1518155 - CVE-2017-16994 kernel: mm/pagewalk.c:walk_hugetlb_range function mishandles holes in hugetlb ranges causing information leak
1519781 - CVE-2017-5754 hw: cpu: speculative execution permission faults handling
1526427 - CVE-2017-17712 kernel: Race condition in raw_sendmsg function allows denial-of-service or kernel addresses leak

Wi-Fi Protected Access (WPA and WPA2) allows re-installation of the Group Temporal Key (GTK) during the group key handshake, allowing an attacker within radio range to replay frames from access points to clients. Jann Horn discovered that the Berkeley Packet Filter (BPF) implementation in the Linux kernel improperly performed sign extension in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.

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.

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.
