Icecast 1.1.x/1.3.x - Slash File Name Denial of Service

source: https://www.securityfocus.com/bid/2933/info

Icecast is an open source audio-streaming server for both Unix and Microsoft Windows systems.

Icecast does not sufficiently sanitize user-supplied input, or sanely handle unexpected input. Upon receiving a request from a user for a file that ends with a slash or period, the server will crash. The behaviour occurs when the remote attacker adds an '/', '\' or '.' to the end the URL they craft to request the file. The request of an existing file is not necessary, as the Icecast server will fail regardless. 

http://localhost:8000/file//

NOTE: File is interpreted by Icecast as the 'root' directory and anything after 'file/' indicates the file request. The character '/' triggers the denial of service.
