"The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as
referenced in the RHSA-2023:1677 advisory.

    The redhat-virtualization-host packages provide the Red Hat Virtualization Host. These packages include
    redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. Red Hat Virtualization Hosts (RHVH)
    are installed using a special build of Red Hat Enterprise Linux with only the packages required to host
    virtual machines. RHVH features a Cockpit user interface for monitoring the host's resources and
    performing administrative tasks.

    The ovirt-node-ng packages provide the Red Hat Virtualization Host. These packages include redhat-release-
    virtualization-host, ovirt-node, and rhev-hypervisor. Red Hat Virtualization Hosts (RHVH) are installed
    using a special build of Red Hat Enterprise Linux with only the packages required to host virtual

    Security Fix(es):

    * git: gitattributes parsing integer overflow (CVE-2022-23521)

    * git: Heap overflow in `git archive`, `git log --format` leading to RCE (CVE-2022-41903)

    * ALSA: pcm: Move rwsem lock inside snd_ctl_elem_read to prevent UAF (CVE-2023-0266)

    * kernel: FUSE filesystem low-privileged user privileges escalation (CVE-2023-0386)

    * nss: Arbitrary memory write via PKCS 12 (CVE-2023-0767)

    other related information, refer to the CVE page(s) listed in the References section.
