(RHSA-2004:451) spamassassin security update

SpamAssassin provides a way to reduce unsolicited commercial email (SPAM)
from incoming email.

A denial of service bug has been found in SpamAssassin versions below 2.64.
A malicious attacker could construct a message in such a way that would
cause spamassassin to stop responding, potentially preventing the delivery
or filtering of email. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0796 to this issue.

Users of SpamAssassin should update to these updated packages which contain
a backported patch and is not vulnerable to this issue.
