    Garth Mollett discovered that OpenStack Nova did not properly clean up an instance when using rescue mode
    with the VMWare driver. A remove authenticated user could exploit this to bypass intended quota limits. By
    default, Ubuntu does not use the VMWare driver. (CVE-2014-3608)

    Amrith Kumar discovered that OpenStack Nova did not properly sanitize log message contents. Under certain
    circumstances, a local attacker with read access to Nova log files could obtain access to sensitive
    information. (CVE-2014-7230)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
