Red Hat Security Advisory: buildah security and bug fix update
Notes
Topic
An update for buildah is now available for Red Hat Enterprise Linux 7 Extras.
Red Hat Product Security has rated this update as having a security impact of Moderate. 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.
Details
The buildah package provides a tool for facilitating building OCI container images. Among other things, buildah enables you to:
* Create a working container, either from scratch or using an image as a starting point.
* Create an image, either from a working container or using the instructions in a Dockerfile.
* Build both Docker and OCI images.
Security Fix(es):
* proglottis/gpgme: Use-after-free in GPGME bindings during container image pull (CVE-2020-8945)
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):
* rootless buildah does not work with UID in /etc/subuid (BZ#1765469)
* Extras RHEL-7.8 update - buildah (BZ#1791286)
* buildah should be linked against gpgme-pthread (BZ#1793074)
