Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
read_ints in plistlib.py in Python through 3.9.1 is vulnerable to a potential DoS attack via CPU and RAM exhaustion when processing malformed Apple Property List files in binary format.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-400

A single request can consume unbounded CPU, memory, or connections, so a modest amount of malicious traffic exhausts the service. The result is denial of service for everyone else. Remediation is enforcing limits, quotas, and timeouts on what any one request can use.

Recommended fix High confidence

Python 3.9.1 or later (or 3.7.10+, 3.8.7+ depending on your major version); prefer Python 3.11.x or 3.12.x for latest security fixes

  1. Identify the current Python version in use by running 'python3 --version' or checking the bundled Python in Active Iq Unified Manager
  2. Upgrade Python to version 3.6.13 or higher (if using Python 3.6), 3.7.10 or higher (if using Python 3.7), 3.8.7 or higher (if using Python 3.8), 3.9.1 or higher (if using Python 3.9), or preferably a modern stable release like 3.11.x or 3.12.x
  3. For Active Iq Unified Manager, check NetApp's support documentation for specific upgrade instructions since it bundles Python; apply any vendor-specific patches or updates
  4. Verify the upgrade was successful by running 'python3 --version' and confirming it matches the target fixed version
  5. Test that plistlib functionality works correctly with both valid and malformed plist files to confirm the vulnerability is remediated
Caveat Minor: Python 3.6 reached end-of-life in December 2021; upgrading to newer Python versions may require code changes for deprecated APIs
