Exim (www.exim.org) is a message transfer agent (MTA) developed at the University of Cambridge for use on Unix systems connected to the Internet. There's a heap overflow in all versions of exim3 and exim4 prior to version 4.21. It can be exercised by anyone who can make an SMTP connection to the exim daemon. The overflow is very limited, and in my opinion it's probably not exploitable. However, it's possible that this will prove to be exploitable for arbitrary command execution on some platforms in some circumstances.
