Updated mailman packages that fix security issues are 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 a program used to help manage email discussion lists.
A flaw was found in the way Mailman handled MIME multipart messages. An
attacker could send a carefully crafted MIME multipart email message to a
mailing list run by Mailman which caused that particular mailing list
to stop working. (CVE-2006-2941)
Several cross-site scripting (XSS) issues were found in Mailman. An
attacker could exploit these issues to perform cross-site scripting attacks
against the Mailman administrator. (CVE-2006-3636)
Red Hat would like to thank Barry Warsaw for disclosing these vulnerabilities.
Users of Mailman should upgrade to these updated packages, which contain
backported patches to correct this issue.
