The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1216 advisory.

    KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on a variety of     architectures. The qemu-kvm-rhev packages provide the user-space component for running virtual machines     that use KVM in environments managed by Red Hat products.

    Security Fix(es):

    * QEMU: slirp: heap buffer overflow during packet reassembly (CVE-2019-14378)

    * QEMU: block: iscsi: OOB heap access via an unexpected response of iSCSI Server (CVE-2020-1711)

    * QEMU: qxl: null pointer dereference while releasing spice resources (CVE-2019-12155)

    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.
