Red Hat Security Advisory
Synopsis: Important: container-tools:rhel8 security and bug fix update
Advisory ID: RHSA-2019:0975-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2019:0975
Issue date: 2019-05-07
CVE Names: CVE-2019-5736
=====================================================================
1. Summary:
An update for the container-tools:rhel8 module is now available for Red Hat
Enterprise Linux 8.
Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE link(s) in the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AppStream (v. 8) – aarch64, noarch, ppc64le, s390x, x86_64
3. 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)
