pip show azure-identity

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-35255, inspect your installed packages using pip:

pip show azure-identity

Analyze the terminal output to locate any version of Azure identity in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.16.1), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition'), where the product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently. In Azure identity, 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.
