SmallHTTP 1.204 through 3.00 beta 8 allows remote attackers to cause a denial of service via multiple long URL requests.

Small HTTP Server 2.01 does not properly process Server Side Includes (SSI) tags that contain null values, which allows local users, and possibly remote attackers, to cause the server to crash by inserting the SSI into an HTML file.

Small HTTP Server 2.01 allows remote attackers to cause a denial of service by connecting to the server and sending out multiple GET, HEAD, or POST requests and closing the connection before the server responds to the requests.

Small HTTP Server 2.03 and earlier allows remote attackers to cause a denial of service by repeatedly requesting a URL that references a directory that does not contain an index.html file, which consumes memory that is not released after the request is completed.
