runc through 1.0-rc6, as used in Docker before 18.09.2 and other products, allows attackers to overwrite the host runc binary (and consequently obtain host root access) by leveraging the ability to execute a command as root within one of these types of containers: (1) a new container with an attacker-controlled image, or (2) an existing container, to which the attacker previously had write access, that can be attached with docker exec. This occurs because of file-descriptor mishandling, related to /proc/self/exe.

HandleRequestAsync in Docker for Windows before 18.06.0-ce-rc3-win68 (edge) and before 18.06.0-ce-win72 (stable) deserialized requests over the \\.\pipe\dockerBackend named pipe without verifying the validity of the deserialized .NET objects. This would allow a malicious user in the "docker-users" group (who may not otherwise have administrator access) to escalate to administrator privileges.
