A NULL pointer dereference flaw was found in the
udevConnectListAllInterfaces() function in libvirt. This issue can occur
when detaching a host interface while at the same time collecting the list
of interfaces via virConnectListAllInterfaces API. This flaw could be used
to perform a denial of service attack by causing the libvirt daemon to
crash.
