Ok, the final patch for this is issue will be the simpler variant that
Eric suggested
The embargo can be considered to be lifted on Monday July 1st, at

The following is the GIT change that DV or myself will apply to libvirt
GIT master immediately before the 1.1.0 release:

Subject: [PATCH] CVE-2013-2218: Fix crash listing network interfaces with
filters
The virConnectListAllInterfaces method has a double-free of the
'struct netcf_if' object when any of the filtering flags cause
an interface to be skipped over. For example when running the
command 'virsh iface-list --inactive'
This is a regression introduced in release 1.0.6 by
commit 7ac2c4fe624f30f2c8270116513fa2ddab07631f
Author: Guannan Ren <gren@redhat.com>
Date: Tue May 21 21:29:38 2013 +0800
interface: list all interfaces with flags == 0

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
