How to Fix CVE-2008-0299

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

paramiko fixed: 1.7.1-3 
pip install paramiko>=1.7.1-3
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 paramiko

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2008-0299, inspect your installed packages using pip:

pip show paramiko

Analyze the terminal output to locate any version of Paramiko in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.7.1-3), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Paramiko, 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

common.py in Paramiko 1.7.1 and earlier, when using threads or forked processes, does not properly use RandomPool, which allows one session to obtain sensitive information from another session by predicting the state of the pool.
