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.
