How to Fix CVE-2014-2573

To remediate this vulnerability, upgrade all affected Nova dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

nova fixed: 12.0.0a0 
pip install nova>=12.0.0a0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show nova

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2014-2573, inspect your installed packages using pip:

pip show nova

Analyze the terminal output to locate any version of Nova in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 12.0.0a0), your application is affected.

Note: The pip show nova command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-770: Allocation of Resources Without Limits or Throttling, where the product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated. In Nova, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The VMWare driver in OpenStack Compute (Nova) 2013.2 through 2013.2.2 does not properly put VMs into RESCUE status, which allows remote authenticated users to bypass the quota limit and cause a denial of service (resource consumption) by requesting the VM be put into rescue and then deleting the image.
