详细描述

cups: CUPS printing system provides a portable printing layer for UNIX® operating systems. This is the package that provides standard lpd emulation.
docker-ce: Docker is an open source project to build, ship and run any application as a lightweight container. Docker containers are both hardware-agnostic and platform-agnostic. This means they can run anywhere, from your laptop to the largest EC2 compute instance and everything in between - and they don't require you to use a particular language, framework or packaging system. That makes them great building blocks for deploying and scaling web apps, databases, and backend services without depending on a particular stack or provider.


Security Fix(es):
cups: A memory corruption issue was addressed with improved validation. This issue is fixed in macOS Catalina 10.15.4. An application may be able to gain elevated privileges.(CVE-2020-3898)
cups: bugfix
docker-ce: A flaw was found in the `userns-remap` feature of Docker. The root user in the remapped namespace can modify files under /var/lib/docker/, leading to possible privilege escalation to the root user in the host. The highest threat from this vulnerability is to data integrity.(CVE-2021-21284)
docker-ce: A flaw was found in Docker. Pulling an intentionally malformed Docker image manifest could lead to a crash of the `dockerd` daemon, resulting in a denial of service. The highest threat from this vulnerability is to system availability.(CVE-2021-21285)
docker-ce: bugfix
