The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:0935 advisory.

    Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies.

    Security Fix(es):

    * It was discovered that 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, or obtain sensitive information from requests     other then their own. (CVE-2016-6816)

    Note: This fix causes Tomcat to respond with an HTTP 400 Bad Request error when request contains     characters that are not permitted by the HTTP specification to appear not encoded, even though they were     previously accepted. The newly introduced system property     tomcat.util.http.parser.HttpParser.requestTargetAllow can be used to configure Tomcat to accept curly     braces ({ and }) and the pipe symbol (|) in not encoded form, as these are often used in URLs without     being properly encoded.

    * A bug was discovered in the error handling of the send file code for the NIO HTTP connector. This led to     the current Processor object being added to the Processor cache multiple times allowing information     leakage between requests including, and not limited to, session ID and the response body. (CVE-2016-8745)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
