virt-who uses world-readable permissions for /etc/sysconfig/virt-who, which allows local users to obtain password for hypervisors by reading the file.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - virt-who uses world-readable permissions for /etc/sysconfig/virt-who, which allows local users to obtain     password for hypervisors by reading the file. (CVE-2014-0189)

Note that Nessus relies on the presence of the package as reported by the vendor.

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)

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 Satellite. With     this update, the agent reads the list of guests when in     VDSM mode correctly and reports to SAM and Satellite as     expected.

  - Previously, virt-who used incorrect information when     connecting to Satellite 5. Consequently, virt-who could     not connect to Satellite 5 servers. The incorrect     parameter has been corrected, and virt- who can now     successfully connect to Satellite 5.

  - 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.

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.

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.

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)
