July 03, 2012

nova vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS
- Ubuntu 11.10

Summary:

Nova could be made to overwrite or corrupt arbitrary files in the
compute host file system.

Software Description:
- nova: OpenStack Compute cloud infrastructure

Details:

Matthias Weckbecker discovered that, when using the OpenStack API to
setup libvirt-based hypervisors, an authenticated user could inject
files in arbitrary locations on the file system of the host running
Nova. A remote attacker could use this to gain root privileges. This
issue only affects Ubuntu 12.04 LTS. (CVE-2012-3360)

P?draig Brady discovered that an authenticated user could corrupt
arbitrary files of the host running Nova. A remote attacker could
use this to cause a denial of service or possibly gain privileges.
(CVE-2012-3361)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
python-nova 2012.1+stable~20120612-3ee026e-0ubuntu1.1

Ubuntu 11.10:
python-nova 2011.3-0ubuntu6.9

In general, a standard system update will make all the necessary changes.
