How to fix?

Upgrade RHEL:7 libvirt-docs to version 0:1.2.8-16.el7 or higher.
This issue was patched in RHSA-2015:0323.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libvirt-docs package and not the libvirt-docs package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
