How to Fix CVE-2012-3446

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

apache-libcloud fixed: 0.11.1 
pip install apache-libcloud>=0.11.1
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 apache-libcloud

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2012-3446, inspect your installed packages using pip:

pip show apache-libcloud

Analyze the terminal output to locate any version of Apache libcloud in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.11.1), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-295: Improper Certificate Validation, where the product does not validate, or incorrectly validates, a certificate. In Apache libcloud, 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

Apache Libcloud before 0.11.1 uses an incorrect regular expression during verification of whether the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via a crafted certificate.
