Ubuntu Security Notice USN-4228-2

Ubuntu Security Notice USN-4228-2
Posted Jan 8, 2020
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 4228-2 - USN-4228-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 ESM. It was discovered that a heap-based buffer overflow existed in the Marvell WiFi-Ex Driver for the Linux kernel. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.

linux-lts-xenial, linux-aws vulnerabilities
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.04 ESM

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-4228-1 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 ESM.

It was discovered that a heap-based buffer overflow existed in the Marvell
WiFi-Ex Driver for the Linux kernel. A physically proximate attacker could
use this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2019-14895, CVE-2019-14901)

It was discovered that a heap-based buffer overflow existed in the Marvell
Libertas WLAN Driver for the Linux kernel. A physically proximate attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2019-14896, CVE-2019-14897)

Anthony Steinhauser discovered that the Linux kernel did not properly
perform Spectre_RSB mitigations to all processors for PowerPC architecture
systems in some situations. A local attacker could use this to expose
sensitive information. (CVE-2019-18660)

It was discovered that Geschwister Schneider USB CAN interface driver in
the Linux kernel did not properly deallocate memory in certain failure
conditions. A physically proximate attacker could use this to cause a
denial of service (kernel memory exhaustion). (CVE-2019-19052)

It was discovered that the driver for memoryless force-feedback input
devices in the Linux kernel contained a use-after-free vulnerability. A
physically proximate attacker could possibly use this to cause a denial of
service (system crash) or execute arbitrary code. (CVE-2019-19524)

It was discovered that the PEAK-System Technik USB driver in the Linux
kernel did not properly sanitize memory before sending it to the device. A
physically proximate attacker could use this to expose sensitive
information (kernel memory). (CVE-2019-19534)

Update instructions:

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

Ubuntu 14.04 ESM:
linux-image-4.4.0-1060-aws 4.4.0-1060.64
linux-image-4.4.0-171-generic 4.4.0-171.200~14.04.1
linux-image-4.4.0-171-generic-lpae 4.4.0-171.200~14.04.1
linux-image-4.4.0-171-lowlatency 4.4.0-171.200~14.04.1
linux-image-4.4.0-171-powerpc-e500mc 4.4.0-171.200~14.04.1
linux-image-4.4.0-171-powerpc-smp 4.4.0-171.200~14.04.1
linux-image-4.4.0-171-powerpc64-emb 4.4.0-171.200~14.04.1
linux-image-4.4.0-171-powerpc64-smp 4.4.0-171.200~14.04.1
linux-image-aws 4.4.0.1060.61
linux-image-generic-lpae-lts-xenial 4.4.0.171.150
linux-image-generic-lts-xenial 4.4.0.171.150
linux-image-lowlatency-lts-xenial 4.4.0.171.150
linux-image-powerpc-e500mc-lts-xenial 4.4.0.171.150
linux-image-powerpc-smp-lts-xenial 4.4.0.171.150
linux-image-powerpc64-emb-lts-xenial 4.4.0.171.150
linux-image-powerpc64-smp-lts-xenial 4.4.0.171.150
linux-image-virtual-lts-xenial 4.4.0.171.150

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.
