   An update that solves four vulnerabilities and has one
   errata is now available.

Description:

   This update for runc fixes the following issues:

   Security vulnerabilities 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
