Description Petr Matousek 2014-09-23 13:17:07 UTC 
If public api virConnectListAllDomains() with second parameter
set to NULL to get only the number of domains is used, it will
lock out all other operations with domains.

A remote attacker able to establish a read-only connection to
libvirtd could use this flaw to cause libvirtd denial of
service.
