Red Hat: Updated spamassassin packages fix a security issue

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. Fixed packages are available from updates.redhat.com.
