A flaw was found in the libvirt nwfilter driver. The
virNWFilterObjListNumOfNWFilters method failed to acquire the
driver->nwfilters mutex before iterating over virNWFilterObj instances.
There was no protection to stop another thread from concurrently modifying
the driver->nwfilters object. This flaw allows a malicious, unprivileged
user to exploit this issue via libvirt’s API virConnectNumOfNWFilters to
crash the network filter management daemon (libvirtd/virtnwfilterd).
