high Nessus Plugin ID 111515

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-2018:2321 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.

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.

The following packages have been upgraded to a later upstream version: imgbased (1.0.22), redhat-release- virtualization-host (4.2), redhat-virtualization-host (4.2). (BZ#1596545, BZ#1607722, BZ#1607723)

Security Fix(es):

* ansible: Inventory variables are loaded from current working directory when running ad-hoc command that can lead to code execution (CVE-2018-10874)

* ansible: ansible.cfg is being read from current working directory allowing possible code execution (CVE-2018-10875)

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 Michael Scherer (OSAS) for reporting CVE-2018-10874. The CVE-2018-10875 issue was discovered by Brian Coca (Red Hat).

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.
