The container-tools module contains tools for working with containers, notably podman, buildah, skopeo, and runc.

Security Fix(es):

  • runc: volume mount race condition with shared mounts leads to information leak/integrity manipulation (CVE-2019-19921)

  • containers/image: Container images read entire image manifest into memory (CVE-2020-1702)

  • podman: incorrectly allows existing files in volumes to be overwritten by a container when it is created (CVE-2020-1726)
