3. Problem description:

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

A flaw was found in the way SpamAssassin processes HTML email containing
URIs. A carefully crafted mail message could cause SpamAssassin to consume
significant resources. If a number of these messages are sent, this could
lead to a denial of service, potentially delaying or preventing the
delivery  of email.
(CVE-2007-0451)

Users of SpamAssassin should upgrade to these updated packages which
contain version 3.1.8 which is not vulnerable to these issues.  

This is an upgrade from SpamAssassin version 3.0.6 to 3.1.8, which contains
many bug fixes and spam detection enhancements. Further details are
available in the SpamAssassin 3.1 changelog and upgrade guide.

4. Solution:
