How to fix?

Upgrade Ubuntu:16.04 docker-registry to version 2.3.0ds1-1ubuntu0.1esm1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream docker-registry package and not the docker-registry package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 relevant fixed versions and status.

A flaw was found in the /v2/_catalog endpoint in distribution/distribution, which accepts a parameter to control the maximum number of records returned (query string: n). This vulnerability allows a malicious user to submit an unreasonably large value for n, causing the allocation of a massive string array, possibly causing a denial of service through excessive use of memory.
