RHSA-2020:4114 - Security Advisory

Topic

An update for openvswitch2.11, ovirt-ansible-repositories, ovn2.11, and python-ovirt-engine-sdk4 is now available for Red Hat Virtualization 4 for Red Hat Enterprise Linux 7 and Red Hat Virtualization Engine 4.3.

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.

Description

ovirt-ansible-repositories is an Ansible role used to set up the repositories required for oVirt engine or host installation.

The openvswitch package contains components for enabling Open vSwitch; a software-based Ethernet virtual switch. It also includes OVN (Open Virtual Network) components for supporting virtual network abstraction.

The Red Hat Virtualization Python SDK is a program that simplifies access to the Red Hat Virtualization API by providing an object-oriented view to developers.

Security Fix(es):

• dpdk: librte_vhost Interger overflow in vhost_user_set_log_base() (CVE-2020-10722)
• dpdk: librte_vhost Integer truncation in vhost_user_check_and_alloc_queue_pair() (CVE-2020-10723)

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):

• Previously, during RHHI-V deployment of 3 hosts using ovirt-ansible-hosted-engine-setup, the Self-Hosted Engine was added to the default cluster, but the additional 2 hosts were not added.

In this release, deployment with ovirt-ansible-hosted-engine-setup successfully adds all hosts to the cluster. (BZ#1855283)

• Previously, when creating large numbers of virtual machines (~2300 VMs), the associated Data Centers became unresponsive, and the hosts did not have Storage Pool Managers (SPM).

With this release, large scale deployment of virtual machines succeeds without errors. (BZ#1849558)
