"This update for containerd, docker, docker-runc,
golang-github-docker-libnetwork, runc fixes the following issues :

Security issues fixed :

CVE-2018-16875: Fixed a CPU Denial of Service (bsc#1118899).

CVE-2018-16874: Fixed a vulnerabity in go get command which could
allow directory traversal in GOPATH mode (bsc#1118898).

CVE-2018-16873: Fixed a vulnerability 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.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
