DESCRIPTION:
Rodrigo Escobar has discovered a vulnerability in Hiawatha, which can
be exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to an error when parsing HTTP header
data. This can be exploited to cause a server to crash via a large
value in the "Content-Length" header.

The vulnerability is confirmed in version 7.4. Other versions may
also be affected.

SOLUTION:
Apply patch (please see the vendor's advisory for details).
