Summary

Mailman is a program used to help manage email discussion lists.
Multiple input sanitization flaws were found in the way Mailman displayed usernames of subscribed users on certain pages. If a user who is subscribed to a mailing list were able to trick a victim into visiting one of those pages, they could perform a cross-site scripting (XSS) attack against the victim. (CVE-2011-0707)
Multiple input sanitization flaws were found in the way Mailman displayed mailing list information. A mailing list administrator could use this flaw to conduct a cross-site scripting (XSS) attack against victims viewing a list's "listinfo" page. (CVE-2010-3089)
Red Hat would like to thank Mark Sapiro for reporting these issues.
Users of mailman should upgrade to this updated package, which contains backported patches to correct these issues.
