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.
