"The remote server runs a version of Icecast, an open source 
streaming audio server that is older than version 1.3.11.

This version is affected by a remote denial of service because
Icecast server does not properly sanitize user-supplied input.

A remote attacker could send a specially crafted URL, by adding '/', 
'\' or '.' to the end, that may result in a loss of availability for 
the service.

*** Nessus reports this vulnerability using only
*** information that was gathered." );

issue." );
