NVD Description

Note: Versions mentioned in the description apply only to the upstream py3-cassandra-medusa package and not the py3-cassandra-medusa package as distributed by Chainguard. See How to fix? for Chainguard 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.
