Apache Tomcat 8.0.x < 8.0.9 Multiple DoS

This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

The remote Apache Tomcat server is affected by multiple denial of
service vulnerabilities.

Description :

According to its self-reported version number, the Apache Tomcat
server running on the remote host is 8.0.x prior to version 8.0.9. It
is, therefore, affected by the following vulnerabilities :

- A flaw in 'ChunkedInputFilter.java' due to improper
handling of attempts to continue reading data after an
error has occurred. A remote attacker, using streaming
data with malformed chunked transfer coding, can
exploit this to conduct HTTP request smuggling or cause
a denial of service. (CVE-2014-0227)

- An error exists due to a failure to limit the size of
discarded requests. A remote attacker can exploit this
to exhaust available memory resources, resulting in a
denial of service condition. (CVE-2014-0230)

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