    Advisory ID:       RHSA-2013:1409-01
    Product:           Red Hat Enterprise Linux
    Advisory URL:      https://rhn.redhat.com/errata/RHSA-2013-1409.html

    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.
    
    This update is available via the Red Hat Network. Details on how to use the
    Red Hat Network to apply this update are available at
