Red Hat Security Advisory: spamassassin security update
Severity
Important
Notes
Topic: Updated spamassassin packages that fix a security issue are now available
for Red Hat Enterprise Linux 4.
This update has been rated as having important security impact by the Red
Hat Security Response Team.
Details: 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.

Apache SpamAssassin before 3.1.8 allows remote attackers to cause a denial of service via long URLs in malformed HTML, which triggers "massive memory usage."
