Alpine: multiple docker packages: security update to 20.10.18-r0

medium Tenable Self-Hosted Container Security Plugin ID 404106

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Moby is an open-source project created by Docker to enable software containerization. A bug was found in
 Moby (Docker Engine) where supplementary groups are not set up properly. If an attacker has direct access
 to a container and manipulates their supplementary group access, they may be able to use supplementary
 group access to bypass primary group restrictions in some cases, potentially gaining access to sensitive
 information or gaining the ability to execute code in that container. This bug is fixed in Moby (Docker
 Engine) 20.10.18. Running containers should be stopped and restarted for the permissions to be fixed. For
 users unable to upgrade, this problem can be worked around by not using the `"USER $USERNAME"` Dockerfile
 instruction. Instead by calling `ENTRYPOINT ["su", "-", "user"]` the supplementary groups will be set up
 properly. (CVE-2022-36109)
