Name        : spamass-milter
Product     : Fedora 12
Version     : 0.3.1
Release     : 18.fc12
URL         : http://savannah.nongnu.org/projects/spamass-milt/
Summary     : Milter (mail filter) for spamassassin
Description :
A milter (Mail Filter) application that pipes incoming mail (including things
received by rmail/UUCP) through SpamAssassin, a highly customizable spam
filter. A milter-compatible MTA such as Sendmail or Postfix is required.

--------------------------------------------------------------------------------
Update Information:

This update includes a fix for a problem where if the milter is running using
the "-x" option to expand aliases before passing inbound mail through
SpamAssassin, a malicious client using a carefully-crafted SMTP session could
execute arbitrary code on the mail server. The fix avoids the use of a shell in
the alias expansion and hence there is no longer a problem with having to
sanitize input from the client.    This problem has been assigned CVE-2010-1132,
which is tracked upstream at https://savannah.nongnu.org/bugs/?29136    The
update also contains improved Received-header-generation for message submission
and a fix for a problem where the milter would erroneously log warnings about
the mail server's configuration when the first message from a non-authenticated
client passed through. As part of the fix for this issue, the required milter
macro configuration for the mail server has changed slightly: see the README
file included in the package for details.
