Red Hat Security Advisory 2013-1302-01 - 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 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.

The updated packages have been upgraded to the 2.3.15 version which is not vulnerable to this issue.
