Bionic 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
* CVE-2021-3587: Denial-of-service when calling sockname() on NFC socket.
If an NFC socket fails to bind, calling getsockname() will result in a
NULL pointer deference. A local, unprivileged user might exploit this to
cause a denial-of-service.
* CVE-2021-3564: Use-after-free when initializing bluetooth HCI device.
A flaw in the bluetooth Host Controller Interface handling could result
in a use-after-free if a device fails initialization. A malicious local
device or user might exploit this to cause a denial-of-service.
* Improved fix to CVE-2019-19036: Denial-of-service in btrfs file system.
Improper validation of file system metadata in the btrfs file system
could lead to a system crash in some situations. An attacker could use
this flaw to construct a malicious btrfs image that, when mounted,
could cause a denial-of-service.
