NVD Description

Note: Versions mentioned in the description apply only to the upstream airflow-2-compat package and not the airflow-2-compat package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

pyOpenSSL is a Python wrapper around the OpenSSL library. Starting in version 0.14.0 and prior to version 26.0.0, if a user provided callback to set_tlsext_servername_callback raised an unhandled exception, this would result in a connection being accepted. If a user was relying on this callback for any security-sensitive behavior, this could allow bypassing it. Starting in version 26.0.0, unhandled exceptions now result in rejecting the connection.
