## Description

The container-tools module contains tools for working with containers, notably podman, buildah, skopeo, and runc.  Security Fix(es):  * A flaw was found in the way runc handled system file descriptors when running containers. A malicious container could use this flaw to overwrite contents of the runc binary and consequently run arbitrary commands on the container host system. (CVE-2019-5736)  For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.  Bug Fix(es):  * [stream rhel8] rebase container-selinux to 2.94 (BZ#1693675)  * [stream rhel8] unable to mount disk at `/var/lib/containers` via `systemd` unit when `container-selinux` policy installed (BZ#1695669)  * [stream rhel8] don't allow a container to connect to random services (BZ#1695689)
