tag_summary = "The remote server runs a version of ICECast, an open source 
streaming audio server, which 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.

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

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