How to fix?

Overview

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

Affected versions of this package are vulnerable to Information Exposure. The code that parsed the HTTP request line permitted invalid characters. This could be exploited, in conjunction with a proxy that also permitted the invalid characters but with a different interpretation, to inject data into the HTTP response. By manipulating the HTTP response the attacker could poison a web-cache, perform an XSS attack and/or obtain sensitive information from requests other then their own.
