LPRng seems to be running.

This daemon has a flaw (until version 3.6.24 at least) that would
let anyone to remotely execute arbitrary commands on the server.

*** Nessus could not remotely determine with certainty that the 
version of LPRng this machine is running is vulnerable or not.

Solution: Make sure that you are running version 3.6.25 or newer 
and filter incoming connections to TCP port 515.

Risk factor : High";

LPRng semble tourner.

Ce daemon (au moins jusqu'a la version 3.6.25) est vulnérable
à un bug permettant d'executer de code arbitraire en tant que
root, à distance.

*** Nessus ne peut déterminer à distance si une version
*** vulnérable tourne

Solution : Assurez-vous de faire tourner LPRng 3.6.25 ou plus récent, filtrez
les connections vers ce port
Facteur de risque : Elevé";
