"According to its self-reported version number, the Apache Tomcat
server running on the remote host is 6.0.x prior to version 6.0.42. It
is, therefore, affected by 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.

Note that Nessus has not tested for this issue but has instead relied
only on the application's self-reported version number.");
