Microsoft has unveiled a patch for a new security breach in its Internet Information Server (IIS) Web server, dubbed the "GET" vulnerability. The company says that the vulnerability could allow denial-of-service attacks to be mounted against web servers using Windows NT Server.
The vulnerability involves the HTTP GET method, which is used to obtain information from the Web server. GET requests that have been purposefully modified can create a denial of service situation that consumes all server resources, causing the machine to hang. This situation cannot happen accidentally.
