"This update for runc fixes the following issues :

Security vulnerablities addressed :

  - 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)

  - CVE-2018-16873: Fix a remote command execution during
    'go get -u' (boo#1118897)

  - CVE-2018-16874: Fix a directory traversal in 'go get'
    via curly braces in import paths (boo#1118898)

  - CVE-2018-16875: Fix a CPU denial of service issue
    (boo#1118899)

Other changes and bug fixes :

  - Update go requirements to >= go1.10

  - Create a symlink in /usr/bin/runc to enable rootless
    Podman and Buildah.

  - Make use of %license macro

  - Remove 'go test' from %check section, as it has only
    ever caused us problems and hasn't (as far as I
    remember) ever caught a release-blocking issue. Smoke
    testing has been far more useful. (boo#1095817)

  - Upgrade to runc v1.0.0~rc6. Upstream changelog is
    available from
    https://github.com/opencontainers/runc/releases/tag/v1.0
    .0-rc6");
