Alpine: multiple docker packages: security update to 20.10.13-r1 (deprecated)

medium Tenable Self-Hosted Container Security Plugin ID 407998

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 and accelerate software containerization. A bug
was found in Moby (Docker Engine) prior to version 20.10.14 where containers were incorrectly started with
non-empty inheritable Linux process capabilities, creating an atypical Linux environment and enabling
programs with inheritable file capabilities to elevate those capabilities to the permitted set during
`execve(2)`. Normally, when executable programs have specified permitted file capabilities, otherwise
unprivileged users and processes can execute those programs and gain the specified file capabilities up to
the bounding set. Due to this bug, containers which included executable programs with inheritable file
capabilities allowed otherwise unprivileged users and processes to additionally gain these inheritable
file capabilities up to the container's bounding set. Containers which use Linux users and groups to
perform privilege separation inside the container are most directly impacted. This bug did not affect the
container security sandbox as the inheritable set never contained more capabilities than were included in
the container's bounding set. This bug has been fixed in Moby (Docker Engine) 20.10.14. Running containers
should be stopped, deleted, and recreated for the inheritable capabilities to be reset. This fix changes
Moby (Docker Engine) behavior such that containers are started with a more typical Linux environment. As a
workaround, the entry point of a container can be modified to use a utility like `capsh(1)` to drop
inheritable capabilities prior to the primary process starting. (CVE-2022-24769)
