RHBA-2013:0117 - Bug Fix Advisory

Topic

Updated xinetd packages that fix one bug are now available for Red Hat
Enterprise Linux 5.

Description

Xinetd is 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. Xinetd
provides extensive logging, has no limit on the number of server arguments, and
allows users to bind specific services to specific IP addresses on a host
machine. Each service has its own specific configuration file for xinetd; the
files are located in the /etc/xinetd.d directory.

This update fixes the following bug:

• Previously, when the xinetd daemon connected to the TCPMUX service, the

service file descriptors were not closed properly. Consequently, xinetd
terminated unexpectedly with a segmentation fault. With this update, the code
has been fixed to close the file descriptors, and xinetd no longer crashes when
a connection to TCPMUX service is established. (BZ#801507)

All users of xinetd are advised to upgrade to these updated packages, which fix
this bug.
