Synopsis:          Moderate: xinetd security update
Advisory ID:       RHSA-2013:1409-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2013:1409.html
Issue date:        2013-10-07
Keywords:          xinetd
CVE Names:         CVE-2013-4342 
====================================================================
1. Summary:

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64
Red Hat Enterprise Linux HPC Node (v. 6) - x86_64
Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64
Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64

3. Description:

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.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
