CRLF injection vulnerability in the tornado.web.RequestHandler.set_header function in Tornado before 2.2.1 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via crafted input.

According to its banner, the version of Tornado installed on the remote host is older than 2.2.1.  As such, it may be affected by an HTTP response splitting vulnerability that may allow an unauthenticated, remote attacker to forge responses from a trusted server.

Update to 2.2.1 which fixes an HTTP header injection vulnerability.
