Ubuntu Security Notice USN-1305-1
December 13, 2011

nova vulnerability

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

- Ubuntu 11.10


Nova could be made to overwrite files.

Software Description:
- nova: OpenStack Compute cloud infrastructure


David Black discovered that Nova did not properly perform input validation
during image registration. An attacker could exploit this by registering a
crafted image using the EC2 API or S3/RegisterImage method and overwrite
files as the nova user.

Update instructions:

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

Ubuntu 11.10:
  python-nova                     2011.3-0ubuntu6.3

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