The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2019:3011 advisory.

The redhat-virtualization-host packages provide the Red Hat Virtualization Host. These packages include     redhat-release-virtualization-host, redhat-virtualization-host, and ovirt-node-ng. 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: imgbased (1.1.10), ovirt-node-ng     (4.3.6), redhat-release-virtualization-host (4.3.6), redhat-virtualization-host (4.3.6). (BZ#1734624,     BZ#1737771, BZ#1752750)

Security Fix(es):

* kernel: hw: Spectre SWAPGS gadget vulnerability (CVE-2019-1125)

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.

Bug Fix(es):

* RHVH 4.3.6: Incorrect welcome info appear in RHVH boot process (BZ#1736798)

* The company logo displays wrong. (BZ#1738457)

Enhancement(s):

* [downstream clone - 4.3.6] [RFE] Warn if SELinux is disabled when upgrading RHV-H (BZ#1744027)

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

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
