Scientific Linux Security Update : virt-who on SL7.x (noarch)

This script is Copyright (C) 2015 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing a security update.

Description :

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.
