Debian 3.0 DSA 376-2 Critical: Exim Buffer Overflow Remote Threat

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.

The exim package included in the previous advisory contained some
documentation files which were installed with incorrect permissions.
This problem is fixed in exim 3.35-1woody2.

For the stable distribution (woody) this problem has been fixed in
exim version 3.35-1woody2 and exim-tls version 3.35-3woody1.

For the unstable distribution (sid) this problem has been fixed in
exim version 3.36-8. The unstable distribution does not contain an
exim-tls package.

We recommend that you update your exim or exim-tls package.
