The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2021:4750 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.

    Security Fix(es):

    * kernel: out-of-bounds write due to a heap buffer overflow in __hidinput_change_resolution_multipliers()     of hid-input.c (CVE-2021-0512)

    * Ansible: ansible-connection module discloses sensitive info in traceback error message (CVE-2021-3620)

    * kernel: Insufficient validation of user-supplied sizes for the MSG_CRYPTO message type (CVE-2021-43267)

    * libssh: NULL pointer dereference in sftpserver.c if ssh_buffer_new returns NULL (CVE-2020-16135)

    For more details about the security issue(s), including the impact, a CVSS score, and other related     information, refer to the CVE page(s) listed in the References section.

    Bug Fix(es):

    * Red Hat Virtualization Host now includes packages from Red Hat Enterprise Linux 8.5. (BZ#1958101)

    * Red Hat Virtualization Host now includes packages from RHGS-3.5.z on RHEL-8 Batch #5. (BZ#1975175)

    * Red Hat Virtualization Host now includes the packages needed for using Managed Block Devices via     cinderlib. (BZ#1983021)

    * Red Hat Virtualization Host now includes openvswitch related packages from Fast Data Path 21.G release.
    (BZ#1998104)

    * Previously it was not possible to upgrade RHVH to version 4.4.8 when custom VDSM hooks were installed on     RHVH. This was caused by the VDSM hooks dependency on the concrete version of VDSM. The current release     allows users to maintain the VDSM dependency manually. In other words, if you want to upgrade from VDSM     X.Y.Z to version A.B.C, you must upgrade all VDSM hooks to the same A.B.C version. (BZ#2004469)
