Descriptions

The (1) qemuDomainMigratePerform and (2) qemuDomainMigrateFinish2 functions in qemu/qemu_driver.c in libvirt do not unlock the domain when an ACL check fails, which allow local users to cause a denial of service via unspecified vectors.

Las funciones (1) qemuDomainMigratePerform y (2) qemuDomainMigrateFinish2 en qemu/qemu_driver.c en libvirt no desbloquea el dominio cuando una comprobación de ACL falla, lo que permite a usuarios locales provocar una denegación de servicio a través de vectores sin especificar.

It was found that QEMU's qemuDomainMigratePerform() and qemuDomainMigrateFinish2() functions did not correctly perform a domain unlock on a failed ACL check. A remote attacker able to establish a connection to libvirtd could use this flaw to lock a domain of a more privileged user, causing a denial of service.
