NVD Description

Note: Versions mentioned in the description apply only to the upstream python-debug package and not the python-debug package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

Python has added a denylist for known compromised certificates to the "ssl" module to ensure user safety even without certificate revocation configured. Known compromised certificates will automatically be rejected regardless of the SSLContext policy configuration.
