Small HTTP Server Non-Existent File DoS Vulnerability

Small HTTP Server is a full service web server. This utility is less than 30Kb and requires minimal system resources.

Small HTTP Server is subject to a denial of service. When making an http request without a filename specified the server will attempt to locate index.html in that particular directory, if index.html does not exist the server will utilize a large amount of system memory . If numerous http requests, again structured without a filename, are sent to the web server, an attacker could cause the server to consume all system memory. A restart of the application is required in order to gain normal functionality.
