Software Description: - nova: OpenStack Compute cloud infrastructure Details: USN-1831-1 fixed a vulnerability in OpenStack Nova. The upstream fix introduced a regression where instances using uncached QCOW2 images would fail to start. This update fixes the problem. We apologize for the inconvenience. Original advisory details: Loganathan Parthipan discovered that Nova did not verify the size of QCOW2 instance storage. An authenticated attacker could exploit this to cause a denial of service by creating an image with a large virtual size with little data, then filling the virtual disk. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.10: python-nova 2012.2.3-0ubuntu2.2 In general, a standard system update will make all the necessary changes.
