Win - IIS large, content-length header DoS

Various people are reporting a potential denial of service found in
IIS 5.0 (and possibly other versions), whereby a remote attacker sends
a content-length header with an extremely large value. As a result,
the server waits for the indicated amount of data to be sent, with
no apparent timeouts.

This vulnerability has not been confirmed. An exploit has been 
published.
