The remote Redhat Enterprise Linux 6 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2013:0499 advisory.

    The xinetd package provides a secure replacement for inetd, the Internet     services daemon. xinetd provides access control for all services based on     the address of the remote host and/or on time of access, and can prevent     denial-of-access attacks.

    When xinetd services are configured with the TCPMUX or TCPMUXPLUS type,     and the tcpmux-server service is enabled, those services are accessible via     port 1. It was found that enabling the tcpmux-server service (it is     disabled by default) allowed every xinetd service, including those that are     not configured with the TCPMUX or TCPMUXPLUS type, to be accessible via     port 1. This could allow a remote attacker to bypass intended firewall     restrictions. (CVE-2012-0862)

    Red Hat would like to thank Thomas Swan of FedEx for reporting this issue.

    This update also fixes the following bugs:

    * Prior to this update, a file descriptor array in the service.c source     file was not handled as expected. As a consequence, some of the descriptors     remained open when xinetd was under heavy load. Additionally, the system     log was filled with a large number of messages that took up a lot of disk     space over time. This update modifies the xinetd code to handle the file     descriptors correctly and messages no longer fill the system log.
    (BZ#790036)

    * Prior to this update, services were disabled permanently when their CPS     limit was reached. As a consequence, a failed bind operation could occur     when xinetd attempted to restart the service. This update adds additional     logic that attempts to restart the service. Now, the service is only     disabled if xinetd cannot restart the service after 30 attempts.
    (BZ#809271)

    All users of xinetd are advised to upgrade to this updated package, which     contains backported patches to correct these issues.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
