  <description>This update for python-cryptography fixes the following issues:

- CVE-2018-10903: The finalize_with_tag API did not enforce a minimum tag
  length. If a user did not validate the input length prior to passing it to
  finalize_with_tag an attacker could craft an invalid payload with a shortened
  tag (e.g. 1 byte) such that they would have a 1 in 256 chance of passing the
  MAC check. GCM tag forgeries could have caused key leakage (bsc#1101820).
