The remote Redhat Enterprise Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2018:1710 advisory.

    The ovirt-node-ng 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):

    * An industry-wide issue was found in the way many modern microprocessor designs have implemented     speculative execution of Load & Store instructions (a commonly used performance optimization). It relies     on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact     that memory read from address to which a recent memory write has occurred may see an older value and     subsequently cause an update into the microprocessor's data cache even for speculatively executed     instructions that never actually commit (retire). As a result, an unprivileged attacker could use this     flaw to read privileged memory by conducting targeted cache side-channel attacks. (CVE-2018-3639)

    Note: This is the redhat-virtualization-host side of the CVE-2018-3639 mitigation.

    Red Hat would like to thank Ken Johnson (Microsoft Security Response Center) and Jann Horn (Google Project     Zero) for reporting this issue.

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.
