(RHSA-2013:1409) Moderate: xinetd security update

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.
