The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:1699 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 following packages have been upgraded to a later upstream version: redhat-release-virtualization-host     (4.3.4), redhat-virtualization-host (4.3.4). (BZ#1721058, BZ#1721062, BZ#1721065)

    Security Fix(es):

    * kernel: tcp: integer ovrtflow while processing SACK blocks allows remote denial of service     (CVE-2019-11477)

    * libvirt: arbitrary file read/exec via virDomainSaveImageGetXMLDesc API (CVE-2019-10161)

    * libvirt: virDomainManagedSaveDefineXML API exposed to readonly clients (CVE-2019-10166)

    * libvirt: arbitrary command execution via virConnectGetDomainCapabilities API (CVE-2019-10167)

    * libvirt: arbitrary command execution via virConnectBaselineHypervisorCPU and     virConnectCompareHypervisorCPU APIs (CVE-2019-10168)

    * Kernel: tcp: excessive resource consumption while processing SACK blocks allows remote denial of service     (CVE-2019-11478)

    * kernel: tcp: excessive resource consumption for TCP connections with low MSS allows remote denial of     service (CVE-2019-11479)
