(RHSA-2007:0075) Important: spamassassin security update

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.
