    (bsc#1118899).

  - CVE-2018-16874: Fixed a vulnerabity in go get command

    which could allow remote code execution when executed
    with -u in GOPATH mode (bsc#1118897).

  - CVE-2019-5736: Effectively copying /proc/self/exe during
    re-exec to avoid write attacks to the host runc binary,
    which could lead to a container breakout (bsc#1121967).

Other changes and fixes :

  - Update shell completion to use Group: System/Shells.

  - Add daemon.json file with rotation logs configuration
    (bsc#1114832)

  - Update to Docker 18.09.1-ce (bsc#1124308) and to to runc
    96ec2177ae84. See upstream changelog in the packaged
    /usr/share/doc/packages/docker/CHANGELOG.md.

  - Update go requirements to >= go1.10 

  - Use -buildmode=pie for tests and binary build
    (bsc#1048046 and bsc#1051429).

  - Remove the usage of 'cp -r' to reduce noise in the build
    logs.
