Ubuntu Security Notice USN-3797-2
October 23, 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-3797-1 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.

Noam Rathaus discovered that a use-after-free vulnerability existed in the
Infiniband implementation in the Linux kernel. An attacker could use this
to cause a denial of service (system crash). (CVE-2018-14734)

It was discovered that an integer overflow existed in the CD-ROM driver of
the Linux kernel. A local attacker could use this to expose sensitive
information (kernel memory). (CVE-2018-16658)

It was discovered that a integer overflow existed in the HID Bluetooth
implementation in the Linux kernel that could lead to a buffer overwrite.
An attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2018-9363)

Yves Younan discovered that the CIPSO labeling implementation in the Linux
kernel did not properly handle IP header options in some situations. A
remote attacker could use this to specially craft network traffic that
could cause a denial of service (infinite loop). (CVE-2018-10938)

Update instructions:

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

Ubuntu 14.04 LTS:
linux-image-4.4.0-1032-aws 4.4.0-1032.35
linux-image-4.4.0-138-generic 4.4.0-138.164~14.04.1
linux-image-4.4.0-138-generic-lpae 4.4.0-138.164~14.04.1
linux-image-4.4.0-138-lowlatency 4.4.0-138.164~14.04.1
linux-image-4.4.0-138-powerpc-e500mc 4.4.0-138.164~14.04.1
linux-image-4.4.0-138-powerpc-smp 4.4.0-138.164~14.04.1
linux-image-4.4.0-138-powerpc64-emb 4.4.0-138.164~14.04.1
linux-image-4.4.0-138-powerpc64-smp 4.4.0-138.164~14.04.1
linux-image-aws 4.4.0.1032.32
linux-image-generic-lpae-lts-xenial 4.4.0.138.118
linux-image-generic-lts-xenial 4.4.0.138.118
linux-image-lowlatency-lts-xenial 4.4.0.138.118
linux-image-powerpc-e500mc-lts-xenial 4.4.0.138.118
linux-image-powerpc-smp-lts-xenial 4.4.0.138.118
linux-image-powerpc64-emb-lts-xenial 4.4.0.138.118
linux-image-powerpc64-smp-lts-xenial 4.4.0.138.118

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.
