Race condition in 'docker cp' in github.com/docker/docker allows creation of arbitrary files
A race condition in the Docker daemon allows an attacker to create arbitrary empty files on the host system during a "docker cp" operation by swapping a destination path with a symbolic link. The affected code is in the daemon package, specifically the openContainerFS and createIfNotExists methods. This is daemon-owned, Linux-specific code and is not intended for external use as a Go library.
