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

The remote version of this software contains a vulnerability which can be 
exploited by malicious local user to gain escalated privileges.

This issue is caused due to a boundary error in the queue utility when 
processing command line arguments. This can cause a stack based buffer 
overflow.

Solution : Update to Sympa version 4.1.3 or newer

Risk factor : Medium";
