Updated libvirt packages fixes security vulnerabilities:

The qemuDomainMigratePerform and 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 (CVE-2014-8136).

The XML getters for for save images and snapshots objects don’t
check ACLs for the VIR_DOMAIN_XML_SECURE flag and might possibly dump
security sensitive information. A remote attacker able to establish
a connection to libvirtd could use this flaw to cause leak certain
limited information from the domain xml file (CVE-2015-0236).

The updated packages provides the latest 1.1.3.9 version whish has
more robust fixes for MDVSA-2015:023 and MDVSA-2015:035.
