    Summary: Tornado XSRF cookie allows side-channel attack against TLS (BREACH attack)

    Details: Tornado before 3.2.2 sends arbitrary responses that contain a fixed CSRF token and may be sent with HTTP compression, which makes it easier for remote attackers to conduct a BREACH attack and determine this token via a series of crafted requests.
