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
0900 UTC

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

7ac2c4fe62 interface: list all interfaces with flags == 0
virConnectListAllInterfaces should support to list all of
interfaces when the value of flags is 0. The behaviour is
consistent with other virConnectListAll* APIs

90430791ae Make driver method names consistent with public APIs
Ensure that all drivers implementing public APIs use a
naming convention for their implementation that matches
the public API name.

eg for the public API   virDomainCreate make sure QEMU
uses qemuDomainCreate and not qemuDomainStart

d407a11eab Dedicated name for sub-driver open/close methods
It will simplify later work if the sub-drivers have dedicated
APIs / field names. ie virNetworkDriver should have
virDrvNetworkOpen and virDrvNetworkClose methods

abe038cfc0 Extend previous check to validate driver struct field names
Ensure that the driver struct field names match the public
API names. For an API virXXXX we must have a driver struct
field xXXXX. ie strip the leading 'vir' and lowercase any
leading uppercase letters.

1c04f99970 Remove spurious whitespace between function name & open brackets
The libvirt coding standard is to use 'function(...args...)'
instead of 'function (...args...)'. A non-trivial number of
places did not follow this rule and are fixed in this patch.

43dbcb1541 interface: always build all available backends
Always build all available backends to avoid bit-rot. At run time we
select the correct backend and load it by attempting netcf first and
then udev.

b871830ac8 interface: fix netcf based backend naming
All other backends for virInterface or other HVs implementations of
virInterface list their own names for the name instead of the generic
'Interface' value. This does the same for the netcf based backend.
Also, report any errors during registration.

b95ad92e05 build: define WITH_INTERFACE for the driver
Based exclusively on work by Eric Blake in a patch posted with the same
subject. However some modifications related to comments and my plans to
add another backend.

Added WITH_INTERFACE as the only automake variable deciding whether to
build the driver and using WITH_NETCF to identify that we're wanting to
use the netcf library as the backend.

* configure.ac: Added with_interface
* src/interface/netcf_driver.c: Renamed..
* src/interface/interface_backend_netcf.c: ..to this to match storage.
* src/interface/netcf_driver.h: Renamed..
* src/interface/interface_driver.h: ..to this.
* daemon/Makefile.am: Respect WITH_INTERFACE and WITH_NETCF.
* libvirt.spec.in: Add RPM support for --with-interface
