Apache Tomcat < 6.0.32 / 7.0.8 NIO Connector DoS

This script is Copyright (C) 2011-2016 Tenable Network Security, Inc.


Synopsis :

The remote web server is affected by a denial of service
vulnerability.

Description :

According to its self-reported version number, the instance of Apache
Tomcat listening on the remote host is prior to 6.0.32 or 7.0.8. It
is, therefore, affected by a denial of service vulnerability. An
error, involving the NIO HTTP connector, exists such that the limit
'maxHttpHeaderSize' is not enforced thereby allowing a denial of
service condition when memory is exhausted.

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