A buffer overflow exists in exim, which is the standard mail transport
agent in Debian. By supplying a specially crafted HELO or EHLO
command, an attacker could cause a constant string to be written past
the end of a buffer allocated on the heap. This vulnerability is not
believed at this time to be exploitable to execute arbitrary code.
