Summary
Important: container-tools:rhel8 security and bug fix update
Details

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)
