CVE-2002-0072

Internet Information Server 4.0-5.1 - Denial of Service via Long URL Null Pointer Dereference

Title source: llm

Description

The w3svc.dll ISAPI filter in Front Page Server Extensions and ASP.NET for Internet Information Server (IIS) 4.0, 5.0, and 5.1 does not properly handle the error condition when a long URL is provided, which allows remote attackers to cause a denial of service (crash) when the URL parser accesses a null pointer.
