The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:1369 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: i386: multiboot OOB access while loading kernel image (CVE-2018-7550)

    * QEMU: cirrus: OOB access when updating VGA display (CVE-2018-7858)

    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.

    Red Hat would like to thank Cyrille Chatras (Orange.com) and CERT-CC (Orange.com) for reporting     CVE-2018-7550 and Ross Lagerwall (Citrix.com) for reporting CVE-2018-7858.

    Bug Fix(es):

    * In certain Red Hat Virtualization (RHV) guest configurations, virtual pass-through devices could not be     removed properly. A reference count leak in the QEMU emulator has been removed, and the affected devices     are now removed reliably. (BZ#1555213)

    * Previously, a raw disk image that was using the --preallocation=full option in some cases could not be     resized. This problem has been fixed and no longer occurs. (BZ#1566587)

    * Due to race conditions in the virtio-blk and virtio-scsi services, the QEMU emulator sometimes     terminated unexpectedly when shutting down. The race conditions have been removed, and QEMU now exits     gracefully. (BZ#1566586)

    * Prior to this update, deleting guest snapshots using the RHV GUI in some cases failed due to an     incorrect image-seeking algorithm. This update fixes the underlying code, and guest snapshots in RHV can     now be deleted successfully. (BZ#1566369)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
