Summary

Updated docker packages fix security vulnerabilities:
Lack of content verification in docker allowed a remote attacker to cause a Denial of Service via a crafted image layer payload, aka gzip bombing (CVE-2017-14992).
The DefaultLinuxSpec function in oci/defaults.go docker did not block /proc/scsi pathnames, which allowed attackers to trigger data loss (when certain older Linux kernels are used) by leveraging Docker container access to write a "scsi remove-single-device" line to /proc/scsi/scsi, aka SCSI MICDROP (CVE-2017-16539).
Container breakout without selinux in enforcing mode (CVE-2018-10892).
The docker package has been updated to version 18.06.1 to fix these issues and other bugs.
Also, the golang package was updated to version 1.11.1 to be able to build the update docker software.
Additionally, the docker-containerd and opencontainers-runc packages have been updated to work with the updated docker package.
