Описание
The virDomainListPopulate function in conf/domain_conf.c in libvirt before 1.2.9 does not clean up the lock on the list of domains, which allows remote attackers to cause a denial of service (deadlock) via a NULL value in the second parameter in the virConnectListAllDomains API command.
A denial of service flaw was found in the way libvirt's virConnectListAllDomains() function computed the number of used domains. A remote attacker able to establish a read-only connection to libvirtd could use this flaw to make any domain operations within libvirt unresponsive.
