Updated redhat-virtualization-host packages that fix several bugs and add various enhancements are now available.

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.

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 (1.0.20), redhat-release-virtualization-host (4.2), redhat-virtualization-host (4.2). (BZ#1590664)

Security Fix(es) :

* ansible: Failed tasks do not honour no_log option allowing for secrets to be disclosed in logs (CVE-2018-10855)

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 Tobias Henkel (BMW Car IT GmbH) for reporting this issue.

Bug Fix(es) :

* Previously, if systems were configured to skip Logical Volume Manager (LVM) clusters, imgbased sees output that is unrelated to the Logical Volumes that are being queried.

As a result, imgbased failed to parse the output, causing Red Hat Virtualization Host updates to fail.

In this release imgbased now ignores output from skipped clusters enabling imgbased LVM commands to return successfully. (BZ#1568414)

Enhancement(s) :

* Starting from version 4.0, Red Hat Virtualization Hosts could not be deployed from Satellite, and therefore could not take advantage of Satellite's tooling features.

In this release, Red Hat Virtualization Hosts can now be deployed from Satellite 6.3.2 and later. (BZ#1484532)

The remote Redhat Enterprise Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2018:2585 advisory.

  - ansible: Failed tasks do not honour no_log option allowing for secrets to be disclosed in logs     (CVE-2018-10855)

  - 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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

An update for ansible is now available for Red Hat Ansible Engine 2.5 for RHEL 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.

Ansible is a simple model-driven configuration management, multi-node deployment, and remote-task execution system. Ansible works over SSH and does not require any software or daemons to be installed on remote nodes. Extension modules can be written in any language and are transferred to managed machines automatically.

The following packages have been upgraded to a newer upstream version:
ansible (2.5.5)

Security fix(es) :

* ansible: Ansible through version 2.5 does not properly honour the no_log option with failed task iterations. When a list of secret items is supplied to a task and a task iteration fails, secrets can be disclosed in logs despite the no_log option being enabled.
(CVE-2018-10855)

Red Hat would like to thank Tobias Henkel (BMW Car IT GmbH) for reporting these issues.

Bug Fix(es) :

* Changed the admin_users config option to not include 'admin' by default as admin is frequently used for a non-privileged account (https://github.com/ansible/ansible/pull/41164)

* aws_s3 - add async support to the action plugin (https://github.com/ansible/ansible/pull/40826)

* aws_s3 - fix decrypting vault files (https://github.com/ansible/ansible/pull/39634)

* ec2_ami - cast the device_mapping volume size to an int (https://github.com/ansible/ansible/pull/40938)

* eos_logging - fix idempotency issues (https://github.com/ansible/ansible/pull/40604)

* cache plugins - a cache timeout of 0 means the cache will not expire.

* ios_logging - fix idempotency issues (https://github.com/ansible/ansible/pull/41029)

* ios/nxos/eos_config - don't retrieve config in running_config when config is provided for diff (https://github.com/ansible/ansible/pull/41400)

* nxos_banner - fix multiline banner issue (https://github.com/ansible/ansible/pull/41026).

* nxos terminal plugin - fix output truncation (https://github.com/ansible/ansible/pull/40960)

* nxos_l3_interface - fix no switchport issue with loopback and svi interfaces (https://github.com/ansible/ansible/pull/37392).

* nxos_snapshot - fix compare_option (https://github.com/ansible/ansible/pull/41386)

Several vulnerabilities have been found in Ansible, a configuration management, deployment, and task execution system :

  - CVE-2018-10855/ CVE-2018-16876     The no_log task flag wasn't honored, resulting in an     information leak.

  - CVE-2018-10875     ansible.cfg was read from the current working directory.

  - CVE-2018-16837     The user module leaked parameters passed to ssh-keygen     to the process environment.

  - CVE-2019-3828     The fetch module was susceptible to path traversal.

It was discovered that Ansible failed to properly handle sensitive information. A local attacker could use those vulnerabilities to extract them. (CVE-2017-7481) (CVE-2018-10855) (CVE-2018-16837) (CVE-2018-16876) (CVE-2019-10156)

It was discovered that Ansible could load configuration files from the current working directory containing crafted commands. An attacker could run arbitrary code as result. (CVE-2018-10874) (CVE-2018-10875)

It was discovered that Ansible fetch module had a path traversal vulnerability. A local attacker could copy and overwrite files outside of the specified destination. (CVE-2019-3828).

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - Ansible: Compromised remote hosts can lead to running commands on the Ansible controller (CVE-2016-9587)

  - An input validation vulnerability was found in Ansible's mysql_user module before 2.2.1.0, which may fail     to correctly change a password in certain circumstances. Thus the previous password would still be active     when it should have been changed. (CVE-2016-8647)

  - Ansible 2.5 prior to 2.5.5, and 2.4 prior to 2.4.5, do not honor the no_log task flag for failed tasks.
    When the no_log flag has been used to protect sensitive data passed to a task from being logged, and that     task does not run successfully, Ansible will expose sensitive data in log files and on the terminal of the     user running Ansible. (CVE-2018-10855)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2018:2184 advisory.
