Subject: exim remote heap overflow, probably not exploitable
Date: Mon, 1 Sep 2003 07:00:34 +0100


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.

Patches:

Full details coming soon to vuln-dev.
