Description
The vulnerability allows a remote attacker to crate empty files and directories on the host.
The vulnerability exists due to a race condition when handling containers with custom configuration. A remote attacker can trick the victim into running a specially crafted Docker or Kubernetes container, which can be used to share a volume between two containers and then exploit a race with os.MkdirAll to create empty files or directories in arbitrary locations in the host filesystem.
Successful exploitation of the vulnerability may allow an attacker to perform a denial of service attack against the host system.
