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 22.0.0 and prior to version 26.0.0, if a user provided callback to set_cookie_generate_callback returned a cookie value greater than 256 bytes, pyOpenSSL would overflow an OpenSSL provided buffer. Starting in version 26.0.0, cookie values that are too long are now rejected.
