                   Red Hat Security Advisory

Synopsis:          Moderate: virt-who security, bug fix, and enhancement update
Advisory ID:       RHSA-2015:0430-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2015-0430.html
Issue date:        2015-03-05
CVE Names:         CVE-2014-0189 

1. Summary:

An updated virt-who package that fixes one security issue, several bugs,
and adds various enhancements is now available for Red Hat Enterprise
Linux 7.

Red Hat Product Security has rated this update as having Moderate security
impact. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available from the CVE link in the
References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Client (v. 7) - noarch
Red Hat Enterprise Linux Server (v. 7) - noarch
Red Hat Enterprise Linux Workstation (v. 7) - noarch

3. Description:

The virt-who package provides an agent that collects information about
virtual guests present in the system and reports them to the
subscription manager.

It was discovered that the /etc/sysconfig/virt-who configuration file,
which may contain hypervisor authentication credentials, was
world-readable. A local user could use this flaw to obtain authentication
credentials from this file. (CVE-2014-0189)

Red Hat would like to thank Sal Castiglione for reporting this issue.

The virt-who package has been upgraded to upstream version 0.11, which
provides a number of bug fixes and enhancements over the previous version.
The most notable bug fixes and enhancements include:

* Support for remote libvirt.
* A fix for using encrypted passwords.
* Bug fixes and enhancements that increase the stability of virt-who.

This update also fixes the following bugs:

* Prior to this update, the virt-who agent failed to read the list of
virtual guests provided by the VDSM daemon. As a consequence, when in VDSM
mode, the virt-who agent was not able to send updates about virtual guests
to Subscription Asset Manager (SAM) and Red Hat Satellite. With this
update, the agent reads the list of guests when in VDSM mode correctly and
reports to SAM and Satellite as expected. (BZ#1153405)

* Previously, virt-who used incorrect information when connecting to Red
Hat Satellite 5. Consequently, virt-who could not connect to Red Hat
Satellite 5 servers. The incorrect parameter has been corrected, and
virt-who can now successfully connect to Red Hat Satellite 5. (BZ#1158859)

* Prior to this update, virt-who did not decode the hexadecimal
representation of a password before decrypting it. As a consequence, the
decrypted password did not match the original password, and attempts to
connect using the password failed. virt-who has been updated to decode the
encrypted password and, as a result, virt-who now handles storing
credentials using encrypted passwords as expected. (BZ#1161607)

In addition, this update adds the following enhancement:

* With this update, virt-who is able to read the list of guests from a
remote libvirt hypervisor. (BZ#1127965)

Users of virt-who are advised to upgrade to this updated package, which
corrects these issues and adds these enhancements.

4. Solution:
