Ubuntu Security Notice USN-1501-1
July 11, 2012

nova vulnerability

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

- Ubuntu 12.04 LTS


Nova could be made to not respond if passed specially crafted input.

Software Description:
- nova: OpenStack Compute cloud infrastructure


Dan Prince discovered that the Nova scheduler, when using
DifferentHostFilter or SameHostFilter, would make repeated database
instance lookup calls based on passed scheduler hints. An authenticated
attacker could use this to cause a denial of service.

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-0ubuntu1.2

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