The Ubuntu security team deemed this advisory irrelevant for Ubuntu:22.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream nodejs package and not the nodejs package as distributed by Ubuntu.
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.
