    Summary: Security update for containerd, docker, docker-runc, golang-github-docker-libnetwork

    Details: This update for containerd, docker, docker-runc, golang-github-docker-libnetwork fixes the following issues: Security issues fixed: - CVE-2020-15257: Fixed a privilege escalation in containerd (bsc#1178969). - CVE-2021-21284: potential privilege escalation when the root user in the remapped namespace has access to the host filesystem (bsc#1181732) - CVE-2021-21285: pulling a malformed Docker image manifest crashes the dockerd daemon (bsc#1181730) Non-security issues fixed: - Update Docker to 19.03.15-ce. See upstream changelog in the packaged /usr/share/doc/packages/docker/CHANGELOG.md. This update includes fixes for bsc#1181732 (CVE-2021-21284) and bsc#1181730 (CVE-2021-21285). - Only apply the boo#1178801 libnetwork patch to handle firewalld on openSUSE. It appears that SLES doesn't like the patch. (bsc#1180401) - Update to containerd v1.3.9, which is needed for Docker v19.03.14-ce and fixes CVE-2020-15257. bsc#1180243 - Update to containerd v1.3.7, which is required for Docker 19.03.13-ce. bsc#1176708 - Update to Docker 19.03.14-ce. See upstream changelog in the packaged /usr/share/doc/packages/docker/CHANGELOG.md. CVE-2020-15257 bsc#1180243 https://github.com/docker/docker-ce/releases/tag/v19.03.14 - Enable fish-completion - Add a patch which makes Docker compatible with firewalld with nftables backend. Backport of https://github.com/moby/libnetwork/pull/2548 (bsc#1178801, SLE-16460) - Update to Docker 19.03.13-ce. See upstream changelog in the packaged /usr/share/doc/packages/docker/CHANGELOG.md. bsc#1176708 - Fixes for %_libexecdir changing to /usr/libexec (bsc#1174075) - Emergency fix: %requires_eq does not work with provide symbols, only effective package names. Convert back to regular Requires. - Update to Docker 19.03.12-ce. See upstream changelog in the packaged /usr/share/doc/packages/docker/CHANGELOG.md. - Use Go 1.13 instead of Go 1.14 because Go 1.14 can cause all sorts of spurrious errors due to Go returning -EINTR from I/O syscalls much more often (due to Go 1.14's pre-emptive goroutine support). - Add BuildRequires for all -git dependencies so that we catch missing dependencies much more quickly. - Update to libnetwork 55e924b8a842, which is required for Docker 19.03.14-ce. bsc#1180243 - Add patch which makes libnetwork compatible with firewalld with nftables backend. Backport of https://github.com/moby/libnetwork/pull/2548 (bsc#1178801, SLE-16460)
