glance fixed: 11.0.0a0 
pip install glance>=11.0.0a0
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 glance

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2015-1881, inspect your installed packages using pip:

pip show glance

Analyze the terminal output to locate any version of Glance in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 11.0.0a0), your application is affected.

Note: The pip show glance 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 Glance, 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

OpenStack Image Registry and Delivery Service (Glance) 2014.2 through 2014.2.2 does not properly remove images, which allows remote authenticated users to cause a denial of service (disk consumption) by creating a large number of images using the task v2 API and then deleting them, a different vulnerability than CVE-2014-9684.
