Hi,

Exim 4.80.1 was released earlier today to fix a remotely triggerable
heap-based buffer overflow vulnerability in DKIM support (enabled by
default).  Here's the announcement as posted to the exim-announce list
(including instructions on how DKIM support may be disabled, and
download links for Exim 4.80.1):

A few distro tracking/updates URLs:

http://codelabs.ru/fbsd/ports/qa/mail/exim/4.80.1
http://security-tracker.debian.org/tracker/CVE-2012-5671
https://bugs.launchpad.net/ubuntu/+source/exim4/+bug/1071694
https://bugzilla.redhat.com/show_bug.cgi?id=869953
http://www.securityfocus.com/bid/56285

Distro vendors had 1 day of advance notice, which some have made use of.
