The remote Red Hat host is missing a security update for buildah.

Description

The remote Redhat Enterprise Linux 7 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2020:1231 advisory.

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)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
