Dario Faggioli discovered that libvirt incorrectly handled the libxl
driver. A local user could possibly use this flaw to cause libvirtd to
crash, resulting in a denial of service, or possibly execute arbitrary
code. This issue only affected Ubuntu 13.10. (CVE-2013-6457)

It was discovered that libvirt contained multiple race conditions in block
device handling. A remote read-only user could use this flaw to cause
libvirtd to crash, resulting in a denial of service. (CVE-2013-6458)

Eric Blake discovered that libvirt incorrectly handled certain ACLs. An
attacker could use this flaw to possibly obtain certain sensitive
information. This issue only affected Ubuntu 13.10. (CVE-2014-0028)
