Scientific Linux Security Update : libvirt on SL6.x i386/x86_64

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

The libvirt library is a C API for managing and interacting with the
virtualization capabilities of Linux and other operating systems. In
addition, libvirt provides tools for remote management of virtualized
systems.

A flaw was found in libvirtd's RPC call handling. An attacker able to
establish a read-only connection to libvirtd could trigger this flaw
with a specially crafted RPC command that has the number of parameters
set to 0, causing libvirtd to access invalid memory and crash.
(CVE-2012-3445)

This update also fixes the following bugs :

- Previously, repeatedly migrating a guest between two
machines while using the tunnelled migration could cause
the libvirt daemon to lock up unexpectedly. The bug in
the code for locking remote drivers has been fixed and
repeated tunnelled migrations of domains now work as
expected.

- Previously, when certain system locales were used by the
system, libvirt could issue incorrect commands to the
hypervisor. This bug has been fixed and the libvirt
library and daemon are no longer affected by the choice
of the user locale.

All users of libvirt are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. After
installing the updated packages, libvirtd will be restarted
automatically.
