The remote host seems to be running sympa, an open source mailing list 
software.

This version of Sympa contains a flaw in the processing of LDAP 
passwords.  An attacker, exploiting this flaw, would need network
access to the webserver.  A successful attack would crash the sympa
application and render it useless.

Solution : Update to version 3.4.4.1 or newer

Risk factor : Medium";
