"The remote Redhat Enterprise Linux 9 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2024:1561 advisory.

    Red Hat build of MicroShift is Red Hat's light-weight Kubernetes orchestration solution designed for edge
    device deployments and is built from the edge capabilities of Red Hat OpenShift. MicroShift is an
    application that is deployed on top of Red Hat Enterprise Linux devices at the edge, providing an
    efficient way to operate single-node clusters in these low-resource environments.

    This advisory contains the RPM packages for Red Hat build of MicroShift 4.15.6. Read the following
    advisory for the container images for this
    release:

    https://access.redhat.com/errata/RHSA-2024:1559

    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.

    All of the bug fixes may not be documented in this advisory. Read the following release notes
    documentation for details about these changes:

    https://access.redhat.com/documentation/en-us/red_hat_build_of_microshift/4.15/html/release_notes/index

    All Red Hat build of MicroShift 4.15 users are advised to use these updated packages and images when they
    are available in the RPM repository.

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.");
