"The remote Redhat Enterprise Linux 9 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2024:10520 advisory.

    Red Hat OpenShift Container Platform is Red Hat's cloud computing
    Kubernetes application platform solution designed for on-premise or private
    cloud deployments.

    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 Container Platform.
    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 4.17.7. Read the following
    advisory for the container images for this release:

    https://access.redhat.com/errata/RHSA-2024:10518

    All Red Hat build of MicroShift 4.17 users are advised to use these updated packages and images when they
    are available in the RPM repository.

    Security Fix(es):

    * runc: file descriptor leak (CVE-2024-21626)

    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.

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.");
