Vulnerability from variot

Microsoft IIS 5.0 and 5.1 allows remote attackers to cause a denial of service (CPU consumption) via an HTTP request with a Host header that contains a large number of "/" (forward slash) characters. Microsoft IIS is reported to be prone to a remotely exploitable denial of service. This condition occurs upon receipt of a malformed HOST field in a HTTP request for 'shtml.dll'. It is possible to reproduce this condition by sending a HTTP POST request with a HOST header field that is composed of an excessive number of slashes (/). Further details are not known at this time
