Details

Aleksa Sarai discovered that Docker was vulnerable to a directory traversal
attack. An attacker could use this vulnerability to read and write arbitrary
files on the host filesystem as root.

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

Ubuntu 19.04
Ubuntu 18.10
Ubuntu 18.04

This update uses a new upstream release, which includes additional bug
fixes. In general, a standard system update will make all the necessary
changes.
