    libvirt vulnerabilities
    A security issue affects these releases of Ubuntu and its derivatives:
    - Ubuntu 14.10
    - Ubuntu 14.04 LTS
    Several security issues were fixed in libvirt.
    Software Description:
    - libvirt: Libvirt virtualization toolkit
    Pavel Hrdina discovered that libvirt incorrectly handled locking when
    processing the virConnectListAllDomains command. An attacker could use this
    issue to cause libvirtd to hang, resulting in a denial of service.
    Eric Blake discovered that libvirt incorrectly handled permissions when
    processing the qemuDomainFormatXML command. An attacker with read-only
    privileges could possibly use this to gain access to certain information
    from the domain xml file. (CVE-2014-7823)
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 14.10:
      libvirt-bin                     1.2.8-0ubuntu11.1
      libvirt0                        1.2.8-0ubuntu11.1
    Ubuntu 14.04 LTS:
      libvirt-bin                     1.2.2-0ubuntu13.1.7
      libvirt0                        1.2.2-0ubuntu13.1.7
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
