The remote CentOS host is missing a security update.
Updated mutt packages that fix a security issue are now available. This update has been rated as having moderate security impact by the Red Hat Security Response Team. Mutt is a text-mode mail user agent. A buffer overflow flaw was found in the way Mutt processes an overly long namespace from a malicious imap server. In order to exploit this flaw a user would have to use Mutt to connect to a malicious IMAP server. (CVE-2006-3242) Users of Mutt are advised to upgrade to these erratum packages, which contain a backported patch to correct this issue.
