Docker Package Upgrade to 18.09.2
Docker released an update to fix a privilege escalation vulnerability (CVE-2019-5736) in runC, the Open Container Initiative (OCI) runtime specification used in Docker Engine and containerd. This vulnerability makes it possible for a malicious actor that has created a specially-crafted container image to gain administrative privileges on the host. Docker recommends immediately applying the update to avoid any potential security threats. For Docker Engine-Community, this means updating to 18.09.2
