Summary
Red Hat Security Advisory: Red Hat Virtualization security, bug fix, and enhancement update

Notes

Topic
An update for redhat-virtualization-host is now available for Red Hat Virtualization 4 for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
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).
