Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:1524 advisory.

The redhat-virtualization-host 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.

Includes GlusterFS fixes for CVE-2018-1088, dhcp fixes for CVE-2018-1111, kernel fixes for CVE-2018-1087, and kernel fixes for CVE-2018-8897.

A list of bugs fixed in this update is available in the Technical Notes book:
https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.2/html/technical_notes/

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.

Solution

Update the affected packages.
