In Soap Lite (aka the SOAP::Lite extension for Perl) 1.14 and earlier,
an example attack consists of defining 10 or more XML entities, each
defined as consisting of 10 of the previous entity, with the document
consisting of a single instance of the largest entity, which expands to
one billion copies of the first entity. The amount of computer memory
used for handling an external SOAP call would likely exceed that
available to the process parsing the XML.
