SCA: security update for github.com/docker/docker, github.com/moby/moby (GHSA-3fwx-pjgw-3558)

medium Tenable Self-Hosted Container Security Plugin ID 432853

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 the data directory (typically `/var/lib/docker`) contained subdirectories with
 insufficiently restricted permissions, allowing otherwise unprivileged Linux users to traverse directory
 contents and execute programs. When containers included executable programs with extended permission bits
 (such as `setuid`), unprivileged Linux users could discover and execute those programs. When the UID of an
 unprivileged Linux user on the host collided with the file owner or group inside a container, the
 unprivileged Linux user on the host could discover, read, and modify those files. This bug has been fixed
 in Moby (Docker Engine) 20.10.9. Users should update to this version as soon as possible. Running
 containers should be stopped and restarted for the permissions to be fixed. For users unable to upgrade
 limit access to the host to trusted users. Limit access to host volumes to trusted containers.
 (CVE-2021-41091)
