Ubuntu Security Notice USN-3631-2
April 24, 2018

linux-lts-xenial, linux-aws vulnerabilities
==========================================================================

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

- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-aws: Linux kernel for Amazon Web Services (AWS) systems
- linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty

Details:

USN-3631-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04
LTS. This update provides the corresponding updates for the Linux
Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu
14.04 LTS.

It was discovered that a buffer overread vulnerability existed in the
keyring subsystem of the Linux kernel. A local attacker could possibly use
this to expose sensitive information (kernel memory). (CVE-2017-13305)

It was discovered that the DM04/QQBOX USB driver in the Linux kernel did
not properly handle device attachment and warm-start. A physically
proximate attacker could use this to cause a denial of service (system
crash) or possibly execute arbitrary code. (CVE-2017-16538)

Luo Quan and Wei Yang discovered that a race condition existed in the
Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel when
handling ioctl()s. A local attacker could use this to cause a denial of
service (system deadlock). (CVE-2018-1000004)

Wang Qize discovered that an information disclosure vulnerability existed
in the SMBus driver for ACPI Embedded Controllers in the Linux kernel. A
local attacker could use this to expose sensitive information (kernel
pointer addresses). (CVE-2018-5750)

范韙飞 discovered that a race condition existed in the Advanced Linux
Sound Architecture (ALSA) subsystem of the Linux kernel that could lead to
a use-after-free or an out-of-bounds buffer access. A local attacker with
access to /dev/snd/seq could use this to cause a denial of service (system
crash) or possibly execute arbitrary code. (CVE-2018-7566)

Update instructions:

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

Ubuntu 14.04 LTS:
linux-image-4.4.0-1017-aws 4.4.0-1017.17
linux-image-4.4.0-121-generic 4.4.0-121.145~14.04.1
linux-image-4.4.0-121-generic-lpae 4.4.0-121.145~14.04.1
linux-image-4.4.0-121-lowlatency 4.4.0-121.145~14.04.1
linux-image-4.4.0-121-powerpc-e500mc 4.4.0-121.145~14.04.1
linux-image-4.4.0-121-powerpc-smp 4.4.0-121.145~14.04.1
linux-image-4.4.0-121-powerpc64-emb 4.4.0-121.145~14.04.1
linux-image-4.4.0-121-powerpc64-smp 4.4.0-121.145~14.04.1
linux-image-aws 4.4.0.1017.17
linux-image-generic-lpae-lts-xenial 4.4.0.121.102
linux-image-generic-lts-xenial 4.4.0.121.102
linux-image-lowlatency-lts-xenial 4.4.0.121.102
linux-image-powerpc-e500mc-lts-xenial 4.4.0.121.102
linux-image-powerpc-smp-lts-xenial 4.4.0.121.102
linux-image-powerpc64-emb-lts-xenial 4.4.0.121.102
linux-image-powerpc64-smp-lts-xenial 4.4.0.121.102

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.
