The version of docker installed on the remote host is prior to 20.10.17-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2022-2022-237 advisory.

  - 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)
