To update your system, please follow these instructions: https://
wiki.ubuntu.com/Security/Upgrades .
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.

To update your system, please follow these instructions: https://
wiki.ubuntu.com/Security/Upgrades .
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.

USN-4228-1: Linux kernel vulnerabilities
7 January 2020
linux, linux-aws, linux-kvm, linux-raspi2, linux-snapdragon vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
o Ubuntu 16.04 LTS
Summary
Several security issues were fixed in the Linux kernel.
Software Description
o linux - Linux kernel
o linux-aws - Linux kernel for Amazon Web Services (AWS) systems
o linux-kvm - Linux kernel for cloud environments
o linux-raspi2 - Linux kernel for Raspberry Pi 2
o linux-snapdragon - Linux kernel for Snapdragon processors
Details
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)
