Systems running Ubuntu 16.04 Xenial can now use Ksplice to patch

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running Ubuntu 16.04
Xenial install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* Use-after-free when writing to SLIP serial line.

A locking error when writing to SLIP serial line while the line is being
closed could lead to a use-after-free. A local attacker could use this
flaw to cause a denial-of-service.


* CVE-2020-2732: Privilege escalation in Intel KVM nested emulation.

Incorrect handling of emulated instructions and IO bitmaps could allow
an unprivileged user in a nested KVM guest instance to crash the system
or potentially, escalate privileges.
