RHEL 5 / 6 : xinetd (RHSA-2013:1409)

This script is Copyright (C) 2013-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

An updated xinetd package that fixes one security issue is now
available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

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.

It was found that xinetd ignored the user and group configuration
directives for services running under the tcpmux-server service. This
flaw could cause the associated services to run as root. If there was
a flaw in such a service, a remote attacker could use it to execute
arbitrary code with the privileges of the root user. (CVE-2013-4342)

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

All xinetd users are advised to upgrade to this updated package, which
contains a backported patch to correct this issue.
