NVD Description

Note: Versions mentioned in the description apply only to the upstream docker-bash-completion package and not the docker-bash-completion package as distributed by SLES. See How to fix? for SLES:15.1 relevant fixed versions and status.

Moby is an open-source project created by Docker to enable software containerization. A bug was found in Moby (Docker Engine) where attempting to copy files using docker cp into a specially-crafted container can result in Unix file permission changes for existing files in the host’s filesystem, widening access to others. This bug does not directly allow files to be read, modified, or executed without an additional cooperating process. This bug has been fixed in Moby (Docker Engine) 20.10.9. Users should update to this version as soon as possible. Running containers do not need to be restarted.
