An updated mailman package that fixes a denial of service flaw is now
available for Red Hat Enterprise Linux 3 and 4.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
Mailman is software to help manage email discussion lists.
A flaw was found in the way Mailman handles MIME multipart messages. An
attacker could send a carefully crafted MIME multipart email message to a
mailing list run by Mailman which would cause that particular mailing list
to stop working. (CVE-2006-0052)
Users of Mailman should upgrade to this updated package, which contains
backported patches to correct this issue.
