  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.

  NOTE: The vendor's perspective is that this is neither a vulnerability nor a bug. The email
  package is intended to have size limits and to throw an exception when limits are exceeded.");

  options are to upgrade to a newer release, disable respective features, remove the product or
  replace the product by another one.

  NOTE: email.utils.parseaddr is categorized as a Legacy API in the documentation of the Python
  email package. Applications should instead use the email.parser.BytesParser or
  email.parser.Parser class.");
