  +==============================================================================+
  | Sqlalchemy-utils from version 0.27.0 'EncryptedType' uses by default AES     |
  | with CBC mode. The IV that it uses is not random though.                     |

  +==============================================================================+
  | UltraJSON (aka ujson) through 5.1.0 has a stack-based buffer overflow in     |
  | Buffer_AppendIndentUnchecked (called from encode). Exploitation can, for     |
  | example, use a large amount of indentation.                                  |
