CVE-2023-36632

[Disputed] A vulnerability was found in Python. This issue occurs in the legacy email.utils.parseaddr function in Python that allows attackers to trigger a "RecursionError: maximum recursion depth exceeded while calling a Python object" via a crafted argument. This argument is plausibly an untrusted value from an application's input data that was supposed to contain a name and an e-mail address.

Red Hat Product Security does not treat this as a security bug because the function is already designed to raise various exceptions like AttributeError, LookupError, OSError, TypeError, UnicodeEncodeError, and ValueError when handling unexpected input. While RecursionError is less common, it occurs due to exceeding the recursion limit, which is an expected behavior in Python for handling deep or malformed input. This error doesn't introduce security risks like unauthorized access, code execution, or other security risks.

Therefore, it is a performance or input handling limitation, not a security vulnerability.
