How to fix?

Upgrade org.apache.tomcat:tomcat-coyote to version 7.0.47, 8.0.0-RC3 or higher.

Overview

org.apache.tomcat:tomcat-coyote is a Tomcat Connectors and HTTP parser.

Affected versions of this package are vulnerable to Information Exposure. Apache Tomcat before 6.0.39, 7.x before 7.0.47, and 8.x before 8.0.0-RC3, when an HTTP connector or AJP connector is used, does not properly handle certain inconsistent HTTP request headers, which allows remote attackers to trigger incorrect identification of a request's length and conduct request-smuggling attacks via (1) multiple Content-Length headers or (2) a Content-Length header and a "Transfer-Encoding: chunked" header.

NOTE: this vulnerability exists because of an incomplete fix for CVE-2005-2090.
