"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).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
