Ubuntu 12.10 : nova regression (USN-1831-2)

high Nessus Plugin ID 66669

Language:

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

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.

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.

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.

Solution

Update the affected python-nova package.
