The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:3061 advisory.

    Kernel-based Virtual Machine (KVM) offers a full virtualization solution for Linux on numerous hardware     platforms. The virt:rhel module contains packages which provide user-space components used to run virtual     machines using KVM. The packages also provide APIs for managing and interacting with the virtualized     systems.

    Security Fix(es):

    * QEMU: msix: OOB access during mmio operations may lead to DoS (CVE-2020-13754)

    * hivex: Buffer overflow when provided invalid node key length (CVE-2021-3504)

    * QEMU: net: an assert failure via eth_get_gso_type (CVE-2020-27617)

    * QEMU: net: infinite loop in loopback mode may lead to stack overflow (CVE-2021-3416)

    * qemu: out-of-bound heap buffer access via an interrupt ID field (CVE-2021-20221)

    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.
